1. Product Overview
The GL-T family consists of 512-Mbit to 1-Gbit, 3.0 V core, Versatile I/O, non-volatile, flash memory devices. These devices have an
8-bit (byte) / 16-bit (word) wide data bus and use only byte / word boundary addresses. All read accesses provide 8/16 bits of data
on each bus transfer cycle. All writes take 8/16 bits of data from each bus transfer cycle.

The GL-T family combines the best features of eXecute In Place (XIP) and Data Storage flash memories. This family has the fast
random access of XIP flash along with the high density and fast program speed of Data Storage flash.
Read access to any random location takes 100 ns to 120 ns depending on device density and I/O power supply voltage. Each
random (initial) access reads an entire 32-byte aligned group of data called a Page. Other words within the same Page may be read
by changing only the low order 4 bits of word address. Each access within the same Page takes 15 ns to 25 ns. This is called Page
Mode read. Changing any of the higher word address bits will select a different Page and begin a new initial access. All read
accesses are asynchronous.

The device control logic is subdivided into two parallel operating sections, the Host Interface Controller (HIC) and the Embedded
Algorithm Controller (EAC). HIC monitors signal levels on the device inputs and drives outputs as needed to complete read and write
data transfers with the host system. HIC delivers data from the currently entered address space on read transfers; places write
transfer address and data information into the EAC command memory; notifies the EAC of power transition, hardware reset, and
write transfers. The EAC looks in the command memory, after a write transfer, for legal command sequences and performs the
related Embedded Algorithms.
Changing the non-volatile data in the memory array requires a complex sequence of operations that are called Embedded
Algorithms (EA). The algorithms are managed entirely by the device internal EAC. The main algorithms perform programming and
erase of the main array data. The host system writes command codes to the flash device address space. The EAC receives the
commands, performs all the necessary steps to complete the command, and provides status information during the progress of an
EA.
The erased state of each memory bit is a logic 1. Programming changes a logic 1 (High) to a logic 0 (Low). Only an Erase operation
is able to change a 0 to a 1. An erase operation must be performed on an entire 128-kbyte aligned and length group of data call a
Sector. When shipped from Cypress all Sectors are erased.
Programming is done via a 512-byte Write Buffer. In x16 it is possible to write from 1 to 256 words, anywhere within the Write Buffer
before starting a programming operation. Within the flash memory array, each 512-byte aligned group of 512 bytes is called a Line.
In x8 it is possible to write from 1 to 256 bytes, anywhere within the Write Buffer before starting a program operation. A programming
operation transfers volatile data from the Write Buffer to a non-volatile memory array Line. The operation is called Write Buffer
Programming.
As the device transfers each 32-byte aligned page of data that was loaded into the Write buffer to the 512-byte Flash array line,
internal logic programs an ECC Code for the Page into a portion of the memory array not visible to the host system software. The
internal logic checks the ECC information during the initial access of every array read operation. If needed, the ECC information
corrects a one bit error during the initial access time.
The Write Buffer is filled with 1’s after reset or the completion of any operation using the Write Buffer. Any locations not written to a 0
by a Write to Buffer command are by default still filled with 1’s. Any 1’s in the Write Buffer do not affect data in the memory array
during a programming operation.
As each Page of data that was loaded into the Write Buffer is transferred to a memory array Line.
Sectors may be individually protected from program and erase operations by the Advanced Sector Protection (ASP) feature set.
ASP provides several, hardware and software controlled, volatile and non-volatile, methods to select which sectors are protected
from program and erase operations.

Software Interface
2. Address Space Overlays
There are several separate address spaces that may appear within the address range of the flash memory device. One address
space is visible (entered) at any given time.
Flash Memory Array: the main non-volatile memory array used for storage of data that may be randomly accessed by
asynchronous read operations.
ID/CFI: a memory array used for Cypress factory programmed device characteristics information. This area contains the Device
Identification (ID) and Common Flash Interface (CFI) information tables.
Secure Silicon Region (SSR): a One Time Programmable (OTP) non-volatile memory array used for Cypress factory programmed
permanent data, and customer programmable permanent data.
Lock Register: an OTP non-volatile word used to configure the ASP features and lock the SSR.
Persistent Protection Bits (PPB): a non-volatile flash memory array with one bit for each Sector. When programmed, each bit
protects the related Sector from erasure and programming.
PPB Lock: a volatile register bit used to enable or disable programming and erasure of the PPB bits.
Array Password: an OTP non-volatile array used to store a 64-bit password used to enable changing the state of the PPB Lock Bit
when using Password Mode sector protection.
SSR3 Password: an OTP non-volatile array used to store a 64-bit password used to enable reading the SSR3.
Dynamic Protection Bits (DYB): a volatile array with one bit for each Sector. When set, each bit protects the related Sector from
erasure and programming.
Status Register: a volatile register used to display Embedded Algorithm status.
Data Polling Status: a volatile register used as an alternate, legacy software compatible, way to display Embedded Algorithm
status.
ECC Status: provides the status of any error detection or correction action taken when reading the selected Page.
The main Flash Memory Array is the primary and default address space but, it may be overlaid by one other address space, at any
one time. Each alternate address space is called an Address Space Overlay (ASO).
Each ASO replaces (overlays) the entire flash device address range. Any address range not defined by a particular ASO address
map, is reserved for future use. All read accesses outside of an ASO address map returns non-valid (undefined) data. The locations
will display actively driven data but the meaning of whatever 1’s or 0’s appear are not defined.
There are four device operating modes that determine what appears in the flash device address space at any given time:
Read Mode
Data Polling Mode
Status Register (SR) Mode
Address Space Overlay (ASO) Mode
In Read Mode the entire Flash Memory Array may be directly read by the host system memory controller. The memory device
Embedded Algorithm Controller (EAC), puts the device in Read mode during Power-on, after a Hardware Reset, after a Command
Reset, or after an Embedded Algorithm (EA) is suspended. Read accesses and command writes are accepted in read mode. A
subset of commands are accepted in read mode when an EA is suspended.
While in any mode, the Status Register read command may be issued to cause the Status Register ASO to appear at every word
address in the device address space. In this Status Register ASO Mode, the device interface waits for a read access and, any write
access is ignored. The next read access to the device accesses the content of the status register, exits the Status Register ASO,
and returns to the previous (calling) mode in which the Status Register read command was received.
In EA mode the EAC is performing an Embedded Algorithm, such as programming or erasing a non-volatile memory array. While in
EA mode, none of the main Flash Memory Array is readable because the entire flash device address space is replaced by the Data
Polling Status ASO. Data Polling Status will appear at every word location in the device address space.
Document Number: 002-00247 Rev. *G
Page 6 of 105
S29GL01GT, S29GL512T
While in EA mode, only a Program / Erase suspend command or the Status Register Read command will be accepted. All other
commands are ignored. Thus, no other ASO may be entered from the EA mode.
When an Embedded Algorithm is suspended, the Data Polling ASO is visible until the device has suspended the EA. When the EA
is suspended the Data Polling ASO is exited and Flash Array data is available. The Data Polling ASO is reentered when the
suspended EA is resumed, until the EA is again suspended or finished. When an Embedded Algorithm is completed, the Data
Polling ASO is exited and the device goes to the previous (calling) mode (from which the Embedded Algorithm was started).
In ASO mode, one of the remaining overlay address spaces is entered (overlaid on the main Flash Array address map). Only one
ASO may be entered at any one time. Commands to the device affect the currently entered ASO. Only certain commands are valid
for each ASO. These are listed in the Table 7.1 on page 48, in each ASO related section of the table.
The following ASOs have non-volatile data that may be programmed to change 1’s to 0’s:
Secure Silicon Region
Lock Register
Persistent Protection Bits (PPB)
Password
Only the PPB ASO has non-volatile data that may be erased to change 0’s to 1’s
When a program or erase command is issued while one of the non-volatile ASOs is entered, the EA operates on the ASO. The ASO
is not readable while the EA is active. When the EA is completed the ASO remains entered and is again readable. Suspend and
Resume commands are ignored during an EA operating on any of these ASOs.

2.2
Device ID and CFI (ID-CFI) ASO
There are two traditional methods for systems to identify the type of flash memory installed in the system. One has traditionally been
called Autoselect and is now referred to as Device Identification (ID). The other method is called Common Flash Interface (CFI).
For ID, a command is used to enable an address space overlay where up to 16 word locations can be read to get JEDEC
manufacturer identification (ID), device ID, and some configuration and protection status information from the flash memory. The
system can use the manufacturer and device IDs to select the appropriate driver software to use with the flash device.
CFI also uses a command to enable an address space overlay where an extendable table of standard information about how the
flash memory is organized and operates can be read. With this method the driver software does not have to be written with the
specifics of each possible memory device in mind. Instead the driver software is written in a more general way to handle many
different devices but adjusts the driver behavior based on the information in the CFI table.
Traditionally these two address spaces have used separate commands and were separate overlays. However, the mapping of these
two address spaces are non-overlapping and so can be combined in to a single address space and appear together in a single
overlay. Either of the traditional commands used to access (enter) the Autoselect (ID) or CFI overlay will cause the now combined
ID-CFI address map to appear.
The ID-CFI address map appears overlays the entire Flash Array.
The ID-CFI address map starts at location 0 of the selected sector. Locations above the maximum defined address of the ID-CFI
ASO to the maximum address of the selected sector have undefined data. The ID-CFI enter commands use the same address and
data values used on previous generation memories to access the JEDEC Manufacturer ID (Autoselect) and Common Flash
Interface (CFI) information, respectively.

2.2.1
Device ID
The Joint Electron Device Engineering Council (JEDEC) standard JEP106T defines the manufacturer ID for a compliant memory.
Common industry usage defined a method and format for reading the manufacturer ID and a device specific ID from a memory
device. The manufacturer and device ID information is primarily intended for programming equipment to automatically match a
device with the corresponding programming algorithm. Cypress has added additional fields within this 32-byte address space.
The original industry format was structured to work with any memory data bus width e. g. x8, x16, x32. The ID code values are
traditionally byte wide but are located at bus width address boundaries such that incrementing the device address inputs will read
successive byte, word, or double word locations with the ID codes always located in the least significant byte location of the data
bus. Because the device data bus is word wide each code byte is located in the lower half of each word location. The original
industry format made the high order byte always 0. Cypress has modified the format to use both bytes in some words of the address
space. For the detail description of the Device ID address map see Table 7.3 on page 55.
2.2.2
Common Flash Memory Interface
The JEDEC Common Flash Interface (CFI) specification (JESD68.01) defines a standardized data structure that may be read from a
flash memory device, which allows vendor-specified software algorithms to be used for entire families of devices. The data structure
contains information for system configuration such as various electrical and timing parameters, and special functions supported by
the device. Software support can then be device-independent, Device ID-independent, and forward-and-backward-compatible for
entire Flash device families.
The system can read CFI information at the addresses within the selected sector as shown in Device ID and Common Flash
Interface (ID-CFI) ASO Map on page 55.
Document Number: 002-00247 Rev. *G
Page 8 of 105
S29GL01GT, S29GL512T
Like the Device ID information, CFI information is structured to work with any memory data bus width e. g. x8, x16, x32. The code
values are always byte wide but are located at data bus width address boundaries such that incrementing the device address reads
successive byte, word, or double word locations with the codes always located in the least significant byte location of the data bus.
Because the data bus is word wide each code byte is located in the lower half of each word location and the high order byte is
always 0.
For further information, please refer to the CFI Specification, Version 1.4 (or later), and the JEDEC publications JEP137-A and
JESD68.01. Please contact JEDEC (www.jedec.org) for their standards and the CFI Specification may be found at the Cypress Web
site (www.cypress.com/spansionappnotes at the time of this document's publication) or by contacting a local Cypress sales office
listed on the web site.
2.3
Status Register ASO
The Status Register ASO contains a single word of registered volatile status for Embedded Algorithms. When the Status Register
read command is issued, the current status is captured (by the rising edge of WE#) into the register and the ASO is entered. The
Status Register content appears on all word locations. The first read access exits the Status Register ASO (with the rising edge of
CE# or OE#) and returns to the address space map in use when the Status Register read command was issued. Write commands
will not exit the Status Register ASO state.
2.4
Data Polling Status ASO
The Data Polling Status ASO contains a single word of volatile memory indicating the progress of an EA. The Data Polling Status
ASO is entered immediately following the last write cycle of any command sequence that initiates an EA. Commands that initiate an
EA are:
Word Program
Program Buffer to Flash

Secure Silicon Region ASO
The Secure Silicon Region (SSR) provides an extra memory area that can be programmed once and permanently protected from
further changes, i. e., it is a One Time Program (OTP) area. The SSR is
2048 bytes in length. It consists of 512 bytes for Factory Locked Secure Silicon Region (SSR0), 1024 bytes for Customer Locked
Secure Silicon Regions (SSR1 and SSR2), and 512 bytes for Customer Locked Secure Silicon Region with Read password (SSR3).
SSR0 is shipped locked, preventing further programming. SSR1 and SSR2 are OTP with each having separate lock bits and once
locked no further programming is allowed for that region. SSR3 is an OTP and requires a SSR3 password to read or program that
region. Once SSR3 is locked no further programming is allowed for that region.

The sector address supplied during the Secure Silicon Entry command selects the Flash Memory Array sector that is overlaid by the
Secure Silicon Region address map. The SSR is overlaid starting at location 0 in the selected sector. Use of the sector 0 address is
recommended for future compatibility. While the SSR ASO is entered the content of all other sectors is memory core data for read
operations. Program is not allowed outside of ASO.

Sector Protection Control
Lock Register ASO
2.6.1
The Lock register ASO contains a single word of OTP memory. When the ASO is entered the Lock Register appears at all word
locations in the device address space. However, it is recommended to read or program the Lock Register only at location 0 of the
device address space for future compatibility.
2.6.2
Persistent Protection Bits (PPB) ASO
The PPB ASO contains one bit of a Flash Memory Array for each Sector in the device. When the PPB ASO is entered, the PPB bit
for a sector appears in the Least Significant Bit (LSB) of each address in the sector. Reading any address in a sector displays data
where the LSB indicates the non-volatile protection status for that sector. However, it is recommended to read or program the PPB
only at address 0 of the sector for future compatibility. If the bit is 0 the sector is protected against programming and erase
operations. If the bit is 1 the sector is not protected by the PPB. The sector may be protected by other features of ASP.
2.6.3
PPB LOCK ASO
The PPB Lock ASO contains a single bit of volatile memory. The bit controls whether the bits in the PPB ASO may be programmed
or erased. If the bit is 0 the PPB ASO is protected against programming and erase operations. If the bit is 1 the PPB ASO is not
protected. When the PPB Lock ASO is entered the PPB Lock bit appears in the least significant bit (LSB) of each address in the
device address space. However, it is recommended to read or program the PPB Lock only at address 0 of the device for future
compatibility.
2.6.4
Password ASO
The Password ASO contains four words of OTP memory. When the ASO is entered the Password appears starting at address 0 in
the device address space. All locations above the fourth word are undefined.
2.6.5
Dynamic Protection Bits (DYB) ASO
The DYB ASO contains one bit of a volatile memory array for each Sector in the device. When the DYB ASO is entered, the DYB bit
for a sector appears in the least significant bit (LSB) of each address in the sector. Reading any address in a sector displays data
where the LSB indicates the non-volatile protection status for that sector. However, it is recommended to read, set, or clear the DYB
only at address 0 of the sector for future compatibility. If the bit is 0 the sector is protected against programming and erase
operations. If the bit is 1 the sector is not protected by the DYB. The sector may be protected by other features of ASP.

ECC Status ASO
The system can access the ECC Status ASO by issuing the ECC Status entry command sequence during Read Mode. The ECC
Status ASO provides the enabled or disabled status of the ECC function or if the ECC function corrected a single-bit Error when
reading the selected Page. Section 5.3, Automatic ECC on page 21 describes the ECC function in more detail.
The ECC Status ASO allows the following activities:
Read ECC Status for the selected Page.
ASO Exit.
2.7.1
ECC Status
The contents of the ECC Status ASO indicate, for the selected ECC Page, whether the ECC logic has corrected an error in the ECC
Page eight bit ECC code, in the ECC page of 32-bytes of data, or that ECC is disabled for that ECC unit. The address specified in
the ECC Status Read Command, provided in Table 7.1 on page 48 and Table 7.2 on page 51, selects the ECC Page.

3. Data Protection
The device offers several features to prevent malicious or accidental modification of any sector via hardware means.
3.1
Device Protection Methods
Power-Up Write Inhibit
3.1.1
RESET#, CE#, WE#, and, OE# are ignored during Power-On Reset (POR). During POR, the device can not be selected, will not
accept commands on the rising edge of WE#, and does not drive outputs. The Host Interface Controller (HIC) and Embedded
Algorithm Controller (EAC) are reset to their standby states, ready for reading array data, during POR. CE# or OE# must go to VIH
before the end of POR (tVCS).
At the end of POR the device conditions are:
all internal configuration information is loaded,
the device is in read mode,
the Status Register is at default value,
all bits in the DYB ASO are set to un-protect all sectors,
the Write Buffer is loaded with all 1’s,
the EAC is in the standby state.
3.1.2
Low V Write Inhibit
CC
When VCC is less than VLKO, the HIC does not accept any write cycles and the EAC resets. This protects data during VCC power-up
and power-down. The system must provide the proper signals to the control pins to prevent unintentional writes when VCC is greater
than VLKO
.
3.2
Command Protection
Embedded Algorithms are initiated by writing command sequences into the EAC command memory. The command memory array is
not readable by the host system and has no ASO. Each host interface write is a command or part of a command sequence to the
device. The EAC examines the address and data in each write transfer to determine if the write is part of a legal command
sequence. When a legal command sequence is complete the EAC will initiate the appropriate EA.
Writing incorrect address or data values, or writing them in an improper sequence, will generally result in the EAC returning to its
Standby state. However, such an improper command sequence may place the device in an unknown state, in which case the
system must write the reset command, or possibly provide a hardware reset by driving the RESET# signal Low, to return the EAC to
its Standby state, ready for random read.
The address provided in each write may contain a bit pattern used to help identify the write as a command to the device. The upper
portion of the address may also select the sector address on which the command operation is to be performed. The Sector Address
(SA) includes Amax through A16 flash address bits (system byte address signals Amax through A16). A command bit pattern is
located in A10 to A0 flash address bits (system byte address signals A11 through A1).
The data in each write may be: a bit pattern used to help identify the write as a command, a code that identifies the command
operation to be performed, or supply information needed to perform the operation. See Table 7.1 on page 48 for a listing of all
commands accepted by the device.
3.3
Secure Silicon Region (OTP)
See Section 2.5, Secure Silicon Region ASO on page 9 for a description of the secure silicon region. See Section 5.4.9.3, Secure
Silicon Region ASO on page 33 for a description of the allowed commands.

3.4
Sector Protection Methods
Write Protect Signal
3.4.1
If WP# = VIL, the lowest or highest address sector is protected from program or erase operations independent of any other ASP
configuration. Whether it is the lowest or highest sector depends on the device ordering option (model) selected. If WP# = VIH, the
lowest or highest address sector is not protected by the WP# signal but it may be protected by other aspects of ASP configuration.
WP# has an internal pull-up; when unconnected, WP# is at VIH. WP# should not change between VIL and VIH during any embedded
operation.
3.4.2
ASP
Advanced Sector Protection (ASP) is a set of independent hardware and software methods used to disable or enable programming
or erase operations, individually, in any or all sectors. This section describes the various methods of protecting data stored in the
memory array. An overview of these methods is shown in Figure 3.1.

9. Volatile Bits: defaults to user choice upon
power-up (see ordering options).
Every main flash array sector has a non-volatile (PPB) and a volatile (DYB) protection bit associated with it. When either bit is 0, the
sector is protected from program and erase operations.
The PPB bits are protected from program and erase when the PPB Lock bit is 0. There are two methods for managing the state of
the PPB Lock bit, Persistent Protection and Password Protection.
Document Number: 002-00247 Rev. *G
Page 13 of 105
S29GL01GT, S29GL512T
The Persistent Protection method sets the PPB Lock to 1 during POR or Hardware Reset so that the PPB bits are unprotected by a
device reset. There is a command to clear the PPB Lock bit to 0 to protect the PPB bits. There is no command in the Persistent
Protection method to set the PPB Lock bit therefore the PPB Lock bit will remain at 0 until the next power-off or hardware reset. The
Persistent Protection method allows boot code the option of changing sector protection by programming or erasing the PPB, then
protecting the PPB from further change for the remainder of normal system operation by clearing the PPB Lock bit. This is
sometimes called Boot-code controlled sector protection.
The Password method clears the PPB Lock bit to 0 during POR or Hardware Reset to protect the PPB. A 64-bit password may be
permanently programmed and hidden for the password method. A command can be used to provide a password for comparison with
the hidden password. If the password matches the PPB Lock bit is set to 1 to unprotect the PPB. A command can be used to clear
the PPB Lock bit to 0.
The selection of the PPB Lock management method is made by programming OTP bits in the Lock Register so as to permanently
select the method used.
The Lock Register also contains OTP bits, for protecting the SSR.
The PPB bits are erased so that all main flash array sectors are unprotected when shipped from Cypress. The Secured Silicon
Region can be factory protected or left unprotected depending on the ordering option (model) ordered.
3.4.3
PPB Lock
The Persistent Protection Bit Lock is a volatile bit for protecting all PPB bits. When cleared to 0, it locks all PPBs and when set to 1,
it allows the PPBs to be changed. There is only one PPB Lock Bit per device.
The PPB Lock command is used to clear the bit to 0. The PPB Lock Bit must be cleared to 0 only after all the PPBs are configured
to the desired settings.
In Persistent Protection mode, the PPB Lock is set to 1 during POR or a hardware reset. When cleared, no software command
sequence can set the PPB Lock, only another hardware reset or power-up can set the PPB Lock bit.
In the Password Protection mode, the PPB Lock is cleared to 0 during POR or a hardware reset. The PPB Lock can only set to 1 by
the Password Unlock command sequence. The PPB Lock can be cleared by the PPB Lock Bit Clear command.
3.4.4
Persistent Protection Bits (PPB)
The Persistent Protection Bits (PPB) are located in a separate nonvolatile flash array. One of the PPB bits is assigned to each
sector. When a PPB is 0 its related sector is protected from program and erase operations. The PPB are programmed individually
but must be erased as a group, similar to the way individual words may be programmed in the main array but an entire sector must
be erased at the same time. Preprogramming and verification prior to erasure are handled by the EAC.
Programming a PPB bit requires the typical word programming time. During a PPB bit programming operation or PPB bit erasing,
Data polling Status DQ6 Toggle Bit I will toggle until the operation is complete. Erasing all the PPBs requires typical sector erase
time.
If the PPB Lock is 0, the PPB Program or erase commands do not execute and time-out without programming or erasing the PPB.
The protection state of a PPB for a given sector can be verified by executing a PPB Status Read command when entered in the PPB
ASO.
3.4.5
Dynamic Protection Bits (DYB)
Dynamic Protection Bits are volatile and unique for each sector and can be individually modified. DYBs only control protection for
sectors that have their PPBs erased. By issuing the DYB Set or Clear command sequences, the DYB are set to 0 or cleared to 1,
thus placing each sector in the protected or unprotected state respectively, if the PPB for that sector is 1. This feature allows
software to easily protect sectors against inadvertent changes, yet does not prevent the easy removal of protection when changes
are needed.
The DYB can be set to 0 or cleared to 1 as often as needed.

3.4.6
Sector Protection States Summary
Each sector can be in one of the following protection states:
Unlocked – The sector is unprotected and protection can be changed by a simple command. The protection state defaults to
unprotected after a power cycle or hardware reset.
Dynamically Locked – A sector is protected and protection can be changed by a simple command. The protection state is not
saved across a power cycle or hardware reset.
Persistently Locked – A sector is protected and protection can only be changed if the PPB Lock Bit is
set to 1. The protection state is non-volatile and saved across a power cycle or hardware reset. Changing the protection state
requires programming or erase of the PPB bits.

The Secure Silicon Region (SSR) protection bits must be used with caution, as once locked, there is no procedure available for
unlocking the protected portion of the Secure Silicon Region and none of the bits in the protected Secure Silicon Region memory
space can be modified in any way. Once the Secure Silicon Region area is protected, any further attempts to program in the area will
fail with status indicating the area being programmed is protected. The Region 0 Indicator Bit is located in the Lock Register at bit
location 0, Region 1 in bit location 6, Region 2 in bit location 9, and Region 3 in bit location 10.

S29GL01GT, S29GL512T
As shipped from the factory, all devices default to the Persistent Protection method, with all sectors unprotected, when power is
applied. The device programmer or host system can then choose which sector protection method to use. Programming either of the
following two, one-time programmable, non-volatile bits, locks the part permanently in that mode:
Persistent Protection Mode Lock Bit (DQ1)
Password Protection Mode Lock Bit (DQ2) If both lock bits are selected to be programmed at the same time, the operation will abort.
Once the Password Mode Lock Bit is programmed, the Persistent Mode Lock Bit is permanently disabled and no changes to the
protection scheme are allowed. Similarly, if the Persistent Mode Lock Bit is programmed, the Password Mode is permanently
disabled.
If the password mode is to be chosen, the password must be programmed prior to setting the corresponding lock register bit. Setting
the Password Protection Mode Lock Bit (DQ2) will disable the ability to program or read the password.
The programming time of the Lock Register is the same as the typical word programming time. During a Lock Register programming
EA, Data polling Status DQ6 Toggle Bit I will toggle until the programming has completed. The system can also determine the status
of the lock register programming by reading the Status Register. See Status Register on page 36 for information on these status
bits.
The user is not required to program DQ2 or DQ1, and DQ6 or DQ0 bits at the same time. This allows the user to lock the SSR before
or after choosing the device protection scheme. When programming the Lock Bits, the Reserved Bits must be 1 (masked).
3.4.8
Persistent Protection Mode
The Persistent Protection method sets the PPB Lock to 1 during POR or Hardware Reset so that the PPB bits are unprotected by a
device reset. There is a command to clear the PPB Lock bit to 0 to protect the PPB. There is no command in the Persistent
Protection method to set the PPB Lock bit to 1 therefore the PPB Lock bit will remain at 0 until the next power-off or hardware reset.
3.4.9
Password Protection Mode
PPB Password Protection Mode
3.4.9.1
PPB Password Protection Mode allows an even higher level of security than the Persistent Sector Protection Mode, by requiring a
64-bit password for setting the PPB Lock. In addition to this password requirement, after power up and reset, the PPB Lock is
cleared to 0 to ensure protection at power-up. Successful execution of the Password Unlock command by entering the entire
password sets the PPB Lock to 1, allowing for sector PPB modifications.
Password Protection Notes:
The Password Program Command is only capable of programming 0’s.
The password is all 1’s when shipped from Cypress. It is located in its own memory space and is accessible through the use of the
Password Program and Password Read commands.
All 64-bit password combinations are valid as a password.
Once the Password is programmed and verified, the Password Mode Locking Bit must be set in order to prevent reading or
modification of the password.
The Password Mode Lock Bit, once programmed, prevents reading the 64-bit password on the data bus and further password
programming. All further read commands to the password region are disabled (data is read as 1’s). There is no means to verify
what the password is after the Password Protection Mode Lock Bit is programmed. Password verification is only allowed before
selecting the Password Protection mode. Any program operation will fail and will report the results as a normal program failure on
a locked sector.
The Password Mode Lock Bit is not erasable.

Page 16 of 105
S29GL01GT, S29GL512T
The exact password must be entered in order for the unlocking function to occur.
– The addresses can be loaded in any order but all 4 words are required for a successful match to occur.
– The Sector Addresses (Amax–A16) and Word Line Addresses (A15–A8) are compared to ‘zero’ while the password address/
data are loaded. If the Sector Address or Word Line Address don’t match then the error will be reported at the end of that write
cycle. The status register will return to the ready state with the Program Status Bit set to 1 and Write Buffer Abort Status Bit set
to 1 indicating a failed programming operation. The data polling status will remain active, with DQ7 set to the complement of
the DQ7 bit in the last word of the password unlock command, and DQ6 toggling. RY/BY# will remain low.
– The specific address and data are compared after the Program Buffer To Flash command has been given. If they don’t match
to the internal set value than the status register will return to the ready state with the Program Status Bit set to 1 indicating a
failed programming operation. The data polling status will remain active, with DQ7 set to the complement of the DQ7 bit in the
last word of the password unlock command, and DQ6 toggling. RY/BY# will remain low. In this error case due to incorrect
password, the device requires a wait time of tPPB and a software reset command to clear the error prior to the Password ASO
Exit command to properly exit the Password ASO. Failure to do so will cause the device to remain in the Password ASO.
The device requires tPPB for setting the PPB Lock after the valid 64-bit password is given to the device.This makes it take an
unreasonably long time (58 million years) for a hacker to run through all the 64-bit combinations in an attempt to correctly match a
password. The EA status checking methods may be used to determine when the EAC is ready to accept a new password
command.
If the password is lost after setting the Password Mode Lock Bit, there is no way to clear the PPB Lock.

4. Read Operations
4.1
Asynchronous Read
Each read access may be made to any location in the memory (random access). Each random access is self-timed with the same
latency from CE# or address to valid data (tACC or tCE).
4.2
Page Mode Read
Each random read accesses an entire 32-byte Page in parallel. Subsequent reads within the same Page have faster read access
speed. The Page is selected by the higher address bits (Amax-A4), while the specific word of that Page is selected by the least
significant address bits A3-A0 (A3-A-1 in x8 mode). The higher address bits are kept constant and only A3-A0 (A3-A-1 in x8 mode)
changed to select a different word in the same Page. This is an asynchronous access with data appearing on DQ15-DQ0 (DQ7-DQ0
in x8 mode) when CE# remains Low, OE# remains Low, and the asynchronous Page access time (tPACC) is satisfied. If CE# goes
High and returns Low for a subsequent access, a random read access is performed and time is required (tACC or tCE).

5. Embedded Operations
5.1
Embedded Algorithm Controller (EAC)
The EAC takes commands from the host system for programming and erasing the flash memory array and performs all the complex
operations needed to change the non-volatile memory state. This frees the host system from any need to manage the program and
erase processes.
There are four EAC operation categories:
Standby (Read Mode)
Address Space Switching
Embedded Algorithms (EA)
Advanced Sector Protection (ASP) Management
5.1.1
EAC Standby
In the standby mode current consumption is greatly reduced. The EAC enters its standby mode when no command is being
processed and no Embedded Algorithm is in progress. If the device is deselected
(CE# = High) during an Embedded Algorithm, the device still draws active current until the operation is completed (ICC3). ICC4 in DC
Characteristics on page 68 represents the standby current specification when both the Host Interface and EAC are in their Standby
state.
5.1.2
Address Space Switching
Writing specific address and data sequences (command sequences) switch the memory device address space from the main flash
array to one of the Address Space Overlays (ASO).
Embedded Algorithms operate on the information visible in the currently active (entered) ASO. The system continues to have access
to the ASO until the system issues an ASO Exit command, performs a Hardware RESET, or until power is removed from the device.
An ASO Exit Command switches from an ASO back to the main flash array address space. The commands accepted when a
particular ASO is entered are listed between the ASO enter and exit commands in the command definitions table. See Command
Summary on page 48 for address and data requirements for all command sequences.
5.1.3
Embedded Algorithms (EA)
Changing the non-volatile data in the memory array requires a complex sequence of operations that are called Embedded
Algorithms (EA). The algorithms are managed entirely by the device internal Embedded Algorithm Controller (EAC). The main
algorithms perform programming and erasing of the main array data and the ASO’s. The host system writes command codes to the
flash device address space. The EAC receives the commands, performs all the necessary steps to complete the command, and
provides status information during the progress of an EA.
5.2
Program and Erase Summary
Flash data bits are erased in parallel in a large group called a sector. The Erase operation places each data bit in the sector in the
logical 1 state (High). Flash data bits may be individually programmed from the erased 1 state to the programmed logical 0 (low)
state. A data bit of 0 cannot be programmed back to a 1. A succeeding read shows that the data is still 0. Only erase operations can
convert a 0 to a 1. Programming the same word location more than once with different 0 bits will result in the logical AND of the
previous data and the new data being programmed. The duration of program and erase operations is shown in Embedded Algorithm
Performance Table on page 44.
Document Number: 002-00247 Rev. *G
Page 19 of 105
S29GL01GT, S29GL512T
Program and erase operations may be suspended.
An erase operation may be suspended to allow either programming or reading of another sector (not in the erase sector). No
other erase operation can be started during an erase suspend.
A program operation may be suspended to allow reading of another location (not in the Line being programmed).
No other program or erase operation may be started during a suspended program operation – program or erase commands will
be ignored during a suspended program operation.
After an intervening program operation or read access is complete the suspended erase or program operation may be resumed.
The resume can happen at any time after the suspend, assuming the device is not in the process of executing another command.
Program and Erase operations may be interrupted as often as necessary but in order for a program or erase operation to
progress to completion there must be some periods of time between resume and the next suspend commands greater than or
equal to tPRS or tERS in Embedded Algorithm Performance Table on page 44.
When an Embedded Algorithm (EA) is complete, the EAC returns to the operation state and address space from which the EA
was started (Erase Suspend, EAC Standby, ...).
The system can determine the status of a program or erase operation by reading the Status Register or using Data Polling Status.
Refer to Status Register on page 36 for information on these status bits. Refer to Data Polling Status on page 37 for more
information.
Any commands written to the device during the Embedded Program Algorithm are ignored except the Program Suspend (x51h),
Status Read command (x70h), and Erase Suspend/Program Suspend command (xB0h).
Any commands written to the device during the Embedded Erase Algorithm are ignored except Status Read (x70h) and Erase
Suspend/Program Suspend command (xB0h).
A hardware reset immediately terminates any in progress program / erase operation and returns to read mode after tRPH time. The
terminated operation should be reinitiated once the device has returned to the idle state, to ensure data integrity.
For performance and reliability reasons reading and programming is internally done on full 32-byte Pages. ICC3 in DC
Characteristics on page 68 represents the active current specification for a write (Embedded Algorithm) operation.
5.2.1
Program Granularity
The S29GL-T supports two methods of programming, Word or Write Buffer Programming. Each Page can be programmed by either
method. Pages programmed by different methods may be mixed within a Line for the Industrial Temperature version (-40°C to
+85°C). For the Industrial Plus version (-40°C to +105°C) and Extended version (-40°C to +125°C) the device will only support one
programming operation on each 32-byte page between erase operations and Single Word Programming command is not supported.
Word programming examines the data word supplied by the command and programs 0’s in the addressed memory array word to
match the 0’s in the command data word.
Write Buffer Programming examines the write buffer and programs 0’s in the addressed memory array Pages to match the 0’s in the
write buffer. The write buffer does not need to be completely filled with data. It is allowed to program as little as a single bit, several
bits, a single word, a few words, a Page, multiple Pages, or the entire buffer as one programming operation. Use of the write buffer
method reduces host system overhead in writing program commands and reduces memory device internal overhead in
programming operations to make Write Buffer Programming more efficient and thus faster than programming individual words with
the Word Programming command.
5.2.2
Incremental Programming
The same word location may be programmed more than once, by either the Word or Write Buffer Programming methods, to
incrementally change 1’s to 0’s. Note that more than one programming operation on the same Page will disable ECC for that Page.

5.3
Automatic ECC
ECC Overview
5.3.1
The Automatic ECC feature works transparently with normal program, erase, and read operations. As the device transfers each
Page of data from the Write Buffer to the memory array, internal ECC logic programs ECC Code for the Page into a portion of the
memory array that is not visible to the host system. The device evaluates the Page data and the ECC Code during each initial Page
access. If needed, the internal ECC logic will correct a one bit error during the initial access.
Programming more than once to a particular Page will disable the ECC function for that Page. The ECC function will remain disabled
for that Page until the next time the host system erases the Sector containing that Page. The host system may read data stored in
that Page following multiple programming operations; however, ECC is disabled and an error in that Page will not be detected or
corrected.
5.3.2
Program and Erase Summary
For performance and reliability reasons, reading and programming operations are performed on full 32-byte Pages in parallel. The
device provides ECC on each Page by adding an ECC Code to each Page when first programmed. The ECC Code is automatic and
transparent to the host system.
5.3.3
ECC Implementation
Each 32-byte Page in the main flash array, as well as each 32-byte OTP region, features an associated ECC Code. Internal ECC
logic is able to detect and correct any single bit error found in a Page, or the associated ECC Code, during a read access.
The first Write Buffer program operation applied to a Page programs the ECC Code for that Page. Subsequent programming
operations, that occur more than once, on a particular Page disable the ECC function for that Page. This allows bit or word
programming; however, note that multiple programming operations to the same Page will disable the ECC function on the Page
where incremental programming occurs. An erase of the Sector containing a Page with ECC disabled will re-enable the ECC
function for that Page.
The ECC function is automatic and transparent to the user. The transparency of the Automatic ECC function enhances data integrity
for typical programming operations that write data once to each Page. The ECC function also facilitates software compatibility to
previous generations of GL Family products by allowing single word programming and bit walking where the same Page or word is
programmed more than once. When a Page has Automatic ECC disabled, the ECC function will not detect or correct an error on a
data read from that Page.
5.3.4
Word Programming
Word programming programs a single word anywhere in the main Flash Memory Array. Programming multiple words in the same
32-byte Page disables Automatic ECC protection on that Page. A sector erase of the sector containing that Page will re-enable
Automatic ECC following multiple word programming operations on that Page.
5.3.5
Write Buffer Programming
Each Write Buffer Program operation allows for programming of 1 bit up to 512 bytes. A 32-byte Page is the smallest program
granularity that features Automatic ECC protection. Programming the same Page more than once will disable the Automatic ECC
function on that Page. Cypress recommends that a Write Buffer programming operation program multiple Pages in an operation and
write each Page only once. This keeps the Automatic ECC protection enabled on each Page. For the very best performance,
program in full Lines of 512 bytes aligned on 512-byte boundaries.

Command Set
5.4.1
Program Methods
5.4.1.1
Word Programming
Word programming is used to program a single word anywhere in the main Flash Memory Array.
The Word Programming command is a four-write-cycle sequence. The program command sequence is initiated by writing two
unlock write cycles, followed by the program set up command. The program address and data are written next, which in turn initiate
the Embedded Word Program algorithm. The system is not required to provide further controls or timing. The device automatically
generates the program pulses and verifies the programmed cell margin internally. When the Embedded Word Program algorithm is
complete, the EAC then returns to its standby mode.
The system can determine the status of the program operation by using Data Polling Status, reading the Status Register, or
monitoring the RY/BY# output. See Status Register on page 36 for information on these status bits. See Data Polling Status
on page 37 for information on these status bits. See Figure 5.1 on page 22 for a diagram of the word programming operation.
Any commands other than Program Suspend written to the device during the Embedded Program algorithm are ignored. Note that a
hardware reset (RESET# = VIL) immediately terminates the programming operation and returns the device to read mode after tRPH
time. To ensure data integrity, the Program command sequence should be reinitiated once the device has completed the hardware
reset operation.
A modified version of the Word Programming command, without unlock write cycles, is used for programming when entered into the
Lock Register, Password, and PPB ASOs or the Unlock Bypass mode. The same command is used to change volatile bits when
entered in to the PPB Lock, and DYB ASOs. See Table 7.1 on page 48 for program command sequences.

5.4.1.2
Write Buffer Programming
A write buffer is used to program data within a 512-byte address range aligned on a 512-byte boundary (Line). Thus, a full Write
Buffer Programming operation must be aligned on a Line boundary. Programming operations of less than a full 512 bytes may start
on any word boundary but may not cross a Line boundary. At the start of a Write Buffer programming operation all bit locations in the
buffer are all 1’s (FFFFh words) thus any locations not loaded will retain the existing data. See Product Overview on page 4 for
information on address map.
Write Buffer Programming allows up to 512 bytes to be programmed in one operation. It is possible to program from 1 bit up to 512
bytes in each Write Buffer Programming operation. It is recommended that a multiple of Pages be written and each Page written only
once. For the very best performance, programming should be done in full Lines of 512 bytes aligned on 512-byte boundaries.
Write Buffer Programming is supported only in the main flash array or the SSR ASO.
The Write Buffer Programming operation is initiated by first writing two unlock cycles. This is followed by a third write cycle of the
Write to Buffer command with the Sector Address (SA), in which programming is to occur. Next, the system writes the number of
word locations minus 1. This tells the device how many write buffer addresses are loaded with data and therefore when to expect the
Program Buffer to flash confirm command. The Sector Address must match in the Write to Buffer command and the Write Word
Count command. The Sector to be programmed must be unlocked (unprotected).
The system then writes the starting address / data combination. This starting address is the first address / data pair to be
programmed, and selects the write-buffer-Line address. The Sector address must match the Write to Buffer Sector Address or the
operation will abort and goes to the Abort state. All subsequent address / data pairs must be in sequential order. All write buffer
addresses must be within the same Line. If the system attempts to load data outside this range, the operation will abort and go to the
Abort state.
The counter decrements for each data load operation. Note that while counting down the data writes, every write is considered to be
data being loaded into the write buffer. No commands are possible during the write buffer loading period. The only way to stop
loading the write buffer is to write with an address that is outside the Line of the programming operation. This invalid address will
immediately abort the Write to Buffer command.
Once the specified number of write buffer locations has been loaded, the system must then write the Program Buffer to Flash
command at the Sector Address. The device then goes busy. The Embedded Program algorithm automatically programs and
verifies the data for the correct data pattern. The system is not required to provide any controls or timings during these operations. If
an incorrect number of write buffer locations have been loaded the operation will abort and goes to the Abort state. The abort occurs
when anything other than the Program Buffer to Flash is written when that command is expected at the end of the word count.
The write-buffer embedded programming operation can be suspended using the Program Suspend command. When the Embedded
Program algorithm is complete, the EAC then returns to the EAC standby or Erase Suspend standby state where the programming
operation was started.
The system can determine the status of the program operation by using Data Polling Status, reading the Status Register, or
monitoring the RY/BY# output. See Status Register on page 36 for information on these status bits. See Data Polling Status
on page 37 for information on these status bits. See Figure 5.2 on page 24 for a diagram of the programming operation.
The Write Buffer Programming Sequence will be aborted under the following conditions:
Load a Word Count value greater than the buffer size (255).
Write an address that is outside the Line provided in the Write to Buffer command.
The Program Buffer to Flash command is not issued after the Write Word Count number of data words is loaded.
When any of the conditions that cause an abort of write buffer command occur the abort will happen immediately after the offending
condition, and will indicate a Program Fail in the Status Register at bit location 4 (PSB = 1) due to Write Buffer Abort bit location 3
(WBASB = 1). The next successful program operation will clear the failure status or a Clear Status Register may be issued to clear
the PSB status bit.
The Write Buffer Programming Sequence can be stopped by the following: Hardware Reset or Power cycle. However, these using
either of these methods may leave the area being programmed in an intermediate state with invalid or unstable data values. In this
case the same area will need to be reprogrammed with the same data or erased to ensure data values are properly programmed or
erased.

5.4.2
Program Suspend / Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming operation so that data can read from
any non-suspended Line. When the Program Suspend command is written during a programming process, the device halts the
programming operation within tPSL (program suspend latency) and updates the status bits. Addresses are don't-cares when writing
the Program Suspend command.
There are two commands available for program suspend. The legacy combined Erase / Program suspend command (B0h command
code) and the separate Program Suspend command (51h command code). There are also two commands for Program resume. The
legacy combined Erase / Program resume command (30h command code) and the separate Program Resume command (50h
command code). It is recommended to use the separate program suspend and resume commands for programming and use the
legacy combined command only for erase suspend and resume.
After the programming operation has been suspended, the system can read array data from any non-suspended Line. The Program
Suspend command may also be issued during a programming operation while an erase is suspended. In this case, data may be
read from any addresses not in Erase Suspend or Program Suspend.
After the Program Resume command is written, the device reverts to programming and the status bits are updated. The system can
determine the status of the program operation by reading the Status Register or using Data Polling. Refer to Status Register
on page 36 for information on these status bits. Refer to Data Polling Status on page 37 for more information.
Accesses and commands that are valid during Program Suspend are:
Read to any other non-erase-suspended sector
Read to any other non-program-suspended Line
Status Read command
Status Register Clear
Exit ASO or Command Set Exit
Program Resume command
Document Number: 002-00247 Rev. *G
Page 26 of 105
S29GL01GT, S29GL512T
The system must write the Program Resume command to exit the Program Suspend mode and continue the programming
operation. Further writes of the Program Resume command are ignored. Another Program Suspend command can be written after
the device has resumed programming.
Program operations can be interrupted as often as necessary but in order for a program operation to progress to completion there
must be some periods of time between resume and the next suspend command greater than or equal to tPRS in Embedded
Algorithm Controller (EAC) on page 19.
Program suspend and resume is not supported while entered in an ASO.
5.4.3
Accelerated Programming
The device supports program operations when the system asserts VHH on the WP#/ACC or ACC pin. When WP#/ACC or ACC pin is
lowered back to VIH or VIL the device exits the Accelerated Programming mode and returns to normal operation. The WP#/ACC is
VHH tolerant but is not designed to accelerate the program functions. If the system asserts VHH on this input, the device
automatically enters the Unlock Bypass mode. The system can then use the Write Buffer Load command sequence provided by the
Unlock Bypass mode. Note that if a ‘Write-to-Buffer-Abort Reset’ is required while in Unlock Bypass mode, the full 3-cycle RESET
command sequence must be used to reset the device. Removing VHH from the ACC input, upon completion of the embedded
program operation, returns the device to normal operation. Note that the WP#/ACC pin must not be at VHH for operations other than
accelerated programming, or device damage may result. WP# contains an internal pull-up; when unconnected, WP# is at VIH.
Accelerated programming is supported at room temperature only.
Sectors must be unlocked prior to raising WP#/ACC to VHH
.
It is recommended that WP#/ACC apply VHH after power-up sequence is completed. In addition, it is recommended that WP#/
ACC apply from VHH to VIH/VIL before powering down VCC/VIO.
5.4.4
Unlock Bypass
This device features an Unlock Bypass mode to facilitate shorter programming commands. Once the device enters the Unlock
Bypass mode, only two write cycles are required to program data, instead of the normal four cycles.The device will also support the
Write to Buffer command and will only require four+ write cycles.
This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total
programming time. The Command Summary on page 48 shows the requirements for the unlock bypass command sequences.
During the unlock bypass mode, only the Read, Program, Write Buffer Programming, Write-to-Buffer-Abort Reset, Status Register
Read, Status Register Clear, Soft Reset, Unlock Bypass Sector Erase, Unlock Bypass Chip Erase, Unlock Erase Suspend/Resume,
Unlock Bypass Suspend/Resume, and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must
issue the two-cycle unlock bypass reset command sequence. The first cycle address is ‘don't care’ and the data 90h. The second
cycle need only contain the data 00h. The sector then returns to the read mode.
Software Functions and Sample Code
The following are C source code examples of using the unlock bypass entry, program, and exit functions. Refer to the Cypress Low
Level Driver User’s Guide for general information on Cypress flash memory software development guidelines.

Evaluate Erase Status
The Evaluate Erase Status (EES) command verifies that the last erase operation on the addressed sector was completed
successfully (i.e. “Trust Worthy”). The EES command can be used to detect erase operations failed due to loss of power, reset, or
failure during the erase operation.
To initiate a EES on a Sector, write 35h to address 555h in the Sector, while the EAC is in the standby state.
The EES command may not be written while the device is actively programming or erasing or suspended.
The EES command does not allow for reads to the array during the operation.
Use the Status Register or Polling method (only DQ6 toggles) to determine if the device is busy or completed. Once completed use
the Status Register read to confirm if the sector is trust worthy or not. Bit 5 of the Status Register (SR[5]) will be cleared to 0 if the
sector is trust worthy. If the sector is not trust worthy than SR[5] will be set to 1, RD/BY# will stay low, and either a Software Reset /
ASO Exit command or a Status Register Clear command is required to return the device to the Standby State.
Once the EES is completed, the EAC will return to the Standby State.
The EES command requires tEES to complete and update the erase status in SR. The DRB bit (SR[7]) may be read to determine
when the EES command is finished. If a sector is found not erased with SR[5]=1, the sector must be erased again to ensure reliable
storage of data in the sector.

5.4.6
Blank Check
The Blank Check command will confirm if the selected main flash array sector is currently erased (i.e. “Trust Worthy” and “Blank”).
The Blank Check command does not allow for reads to the array during the Blank Check. Reads to the array while this command is
executing will return polling data.
To initiate a Blank Check on a Sector, write 33h to address 555h in the Sector, while the EAC is in the standby state.
The Blank Check command may not be written while the device is actively programming or erasing or suspended.
Use the Status Register or Polling method (equivalent to an embedded erase operation) to determine if the device is busy or
completed. Once completed the Status Register and the Polling method will display if the sector is blank (equivalent to a successful
erase operation) or if the sector is not erased. Bit 5 of the Status Register (SR[5]) will be cleared to 0 if the sector is blank. If the
sector is not blank than SR[5] will be set to 1, RD/BY# will stay low, and either a Software Reset / ASO Exit command or a Status
Register Clear command is required to return the device to the Standby State.
As soon as any bit is found to not be erased, the device will halt the operation and report the results.
Once the Blank Check is completed, the EAC will return to the Standby State.
5.4.7
Erase Methods
Chip Erase
5.4.7.1
The chip erase function erases the entire main Flash Memory Array. The device does not require the system to preprogram prior to
erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for an all 0 data pattern prior to
electrical erase. After a successful chip erase, all locations within the device contain FFFFh. The system is not required to provide
any controls or timings during these operations. The chip erase command sequence is initiated by writing two unlock cycles,
followed by a set up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn
invokes the Embedded Erase algorithm. When WE# goes high, at the end of the 6th cycle, the RY/BY# goes low.
When the Embedded Erase algorithm is complete, the EAC returns to the standby state. Note that while the Embedded Erase
operation is in progress, the system can not read data from the device. The system can determine the status of the erase operation
by reading the RY/BY#, Status Register or using Data Polling. Refer to Ready/Busy# (RY/BY#) on page 61 for information on RY/
BY#. Refer to Status Register on page 36 for information on these status bits. Refer to Data Polling Status on page 37 for more
information.
Once the chip erase operation has begun, only a Status Read, Hardware RESET or Power cycle are valid. All other commands are
ignored. However, a Hardware Reset or Power Cycle immediately terminates the erase operation and returns to read mode after
tRPH time. If a chip erase operation is terminated, the chip erase command sequence must be reinitiated once the device has
returned to the idle state to ensure data integrity.
See Table 5.7 on page 44, Asynchronous Write Operations on page 82 and Alternate CE# Controlled Write Operations on page 88
for parameters and timing diagrams.
Sectors protected by the ASP DYB and PPB bits will not be erased. See ASP on page 13. If a sector is protected during chip erase,
chip erase will skip the protected sector and continue with next sector erase. The status register erase status bit and sector lock bit
are not set to 1 by a failed erase on a protected sector.

S29GL01GT, S29GL512T
5.4.7.2
Sector Erase
The sector erase function erases one sector in the memory array. The device does not require the system to preprogram prior to
erase. The Embedded Erase algorithm automatically programs and verifies the entire sector for an all 0 data pattern prior to
electrical erase. After a successful sector erase, all locations within the erased sector contain FFFFh. The system is not required to
provide any controls or timings during these operations. The sector erase command sequence is initiated by writing two unlock
cycles, followed by a set up command. Two additional unlock write cycles are then followed by the address of the sector to be
erased, and the sector erase command. When WE# goes high, at the end of the 6th cycle, the RY/BY# goes low.
After the command sequence is written, a sector erase time-out of tSEA occurs. During the time-out period, additional sector
addresses and sector erase commands may be written. Invalid commands will be ignored during the time-out period. Loading the
sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time
between these additional cycles must be less than tSEA, otherwise erasure may begin. Any sector erase address and command
following the exceeded time-out may or may not be accepted. It is recommended that processor interrupts be disabled during this
time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. Note
that the Secured Silicon Sector, autoselect, and CFI functions are unavailable when an erase operation in is progress. The system
must rewrite the command sequence and any additional addresses and commands.
The system can determine the status of the erase operation by reading the RY/BY#, Status Register or using Data Polling. Refer to
Ready/Busy# (RY/BY#) on page 61 for information on RY/BY#. Refer to Status Register on page 36 for information on these status
bits. Refer to Data Polling Status on page 37 for more information.
Once the sector erase operation has begun, the Status Register Read and Erase Suspend commands are valid. All other
commands are ignored. However, note that a hardware reset immediately terminates the erase operation and returns to read mode
after tRPH time. If a sector erase operation is terminated, the sector erase command sequence must be reinitiated once the device
has reset operation to ensure data integrity.
Sector(s) protected by the ASP DYB and PPB bits or Password Protection will not be erased. See ASP on page 13. If a sector is
protected during multi-sector erase, sector erase will skip the protected sector and continue with next sector erase. The status
register erase status bit and sector lock bit are not set to 1 by a failed erase on a protected sector. See Embedded Algorithm
Controller (EAC) on page 19 for parameters and timing diagrams. Sectors protected by the ASP DYB and PPB bits will not be
erased. See ASP on page 13.

5.4.8
Erase Suspend / Erase Resume
The Erase Suspend command allows the system to interrupt a sector erase operation and then read data from, or program data to,
the main flash array. This command is valid only during sector erase or program operation. The Erase Suspend command is ignored
if written during the chip erase operation.
When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of tESL (erase
suspend latency) to suspend the erase operation and update the status bits.
After the erase operation has been suspended, the part enters the erase-suspend mode. The system can read data from or program
data to the main flash array. Reading at any address within erase-suspended sectors produces undetermined data. The system can
determine if a sector is actively erasing or is erase-suspended by reading the Status Register or using Data Polling. Refer to Status
Register on page 36 for information on these status bits. Refer to Data Polling Status on page 37 for more information.
After an erase-suspended program operation is complete, the EAC returns to the erase-suspend state. The system can determine
the status of the program operation by reading the Status Register, just as in the standard program operation.
If a program failure occurs during erase suspend the Status Register Clear or Soft Reset commands will return the device to the
erase suspended state. Erase will need to be resumed and completed before again trying to program the memory array.
Accesses and commands that are valid during Erase Suspend are:
Read to any other non-suspended sector
Program to any other non-suspended sector
Status Register Read
Status Register Clear
Erase Resume command
To resume the sector erase operation, the system must write the Erase Resume command. The device will revert to erasing and the
status bits will be updated. Further writes of the Resume command are ignored. Another Erase Suspend command can be written
after the chip has resumed erasing.
Erase suspend and resume is not supported while entered in an ASO.
5.4.9
ASO Entry and Exit
ID-CFI ASO
5.4.9.1
The system can access the ID-CFI ASO by issuing the ID-CFI Entry command sequence during Read Mode. See the detail
description Table 7.3 on page 55.
The ID-CFI ASO allows the following activities:
Read ID-CFI ASO, using the same SA as used in the entry command.
Read Sector Protection State at Sector Address (SA) + 2h. Location 2h provides volatile information on the current state of sector
protection for the sector addressed. Bit 0 of the word at location 2h shows the logical NAND of the PPB and DYB bits related to
the addressed sector such that if the sector is protected by either the PPB=0 or the DYB=0 bit for that sector the state shown is
protected. (1= Sector protected, 0= Sector unprotected.)
ASO Exit.
The following is a C source code example of using the CFI Entry and Exit functions. Refer to the Cypress Low Level Driver User's
Guide for general information on Cypress flash memory software development guidelines.
/* Example: CFI Entry command */
*( (UINT16 *)base_addr + 0x55 ) = 0x0098; /* write CFI entry command */
/* Example: CFI Exit command */
*( (UINT16 *)base_addr + 0x000 ) = 0x00F0; /* write cfi exit command */

5.4.9.2
Status Register ASO
The Status Register ASO contains a single word of registered volatile status for Embedded Algorithms. When the Status Register
read command is issued, the current status is captured (by the rising edge of WE#) into the register and the ASO is entered. The
Status Register content appears on all word locations. The first read access exits the Status Register ASO (with the rising edge of
CE# or OE#) and returns to the address space map in use when the Status Register read command was issued. Write commands
will not exit the Status Register ASO state.
5.4.9.3
Secure Silicon Region ASO
The system can access the Secure Silicon Region by issuing the Secure Silicon Region Entry command sequence during Read
Mode. This entry command uses the Sector Address (SA) in the command to determine which sector will be overlaid.
The Secure Silicon Region ASO allows the following activities:
Read Secure Silicon Regions.
Program the customer Secure Silicon Region is allowed using the Word or Write Buffer Programming commands. The Unlock
Bypass commands and using ACC is not allowed.
ASO Exit using legacy Secure Silicon Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.
The recommended procedure for using the SSR region 3 read password mode is as follows:
Program the data you want in SSR region 3.
Clear lock register bit 10 to 0, which disable further program operations.
Program the SSR region 3 password.
Clear lock register bit 11 to 0, which will enable the SSR region 3 password feature which requires that a password be applied
before reading SSR region 3 is allowed.
5.4.9.4
Lock Register ASO
The system can access the Lock Register by issuing the Lock Register entry command sequence during Read Mode. This entry
command does not use a sector address from the entry command. The Lock Register appears at word location 0 in the device

ASO Exit using the common exit command for all ASO — alternative for a consistent exit method.
5.4.9.5
ECC Status ASO
The system can access the ECC Status ASO by issuing the ECC Status entry command sequence during Read Mode. The ECC
Status ASO provides the enabled or disabled status of the ECC function for a specific Page or if the ECC logic corrected a Single Bit
Error the selected Page.
The ECC Status ASO allows the following activities:
Read ECC Status for the selected page.

5.4.9.6
Password ASO
The system can access the Password ASO by issuing the Password entry command sequence during Read Mode. This entry
command does not use a sector address from the entry command. The Password appears at word locations 0 to 3 in the device
address space. All other locations in the device address space are undefined.

ASO Exit using the common exit command for all ASO — alternative for a consistent exit method.
5.4.9.7
PPB ASO
The system can access the PPB ASO by issuing the PPB entry command sequence during Read Mode. This entry command does
not use a sector address from the entry command. The PPB bit for a sector appears in bit 0 of all word locations in the sector.
The PPB ASO allows the following activities:
Read PPB protection status of a sector in bit 0 of any word in the sector.
Program the PPB bit using a modified Word Programming command.
Erase all PPB bits with the PPB erase command.
ASO Exit using legacy Command Set Exit command for backward software compatibility.

Software (Command) Reset / ASO exit
Software reset is part of the command set (See Table 7.1, Command Definitions x16 on page 48) that also returns the EAC to
standby state and must be used for the following conditions:
Exit ASO modes
Clear timeout bit (DQ5) for data polling when timeout occurs
Software Reset does not affect EA mode. Reset commands are ignored once programming or erasure has begun, until the
operation is complete. Software Reset does not affect outputs; it serves primarily to return to Read Mode from an ASO mode or from
a failed program or erase operation.
Software Reset may cause a return to Read Mode from undefined states that might result from invalid command sequences.
However, a Hardware Reset may be required to return to normal operation from some undefined states.
There is no software reset latency requirement. The reset command is executed during the tWPH period.
5.4.9.11
Continuity Check Feature
The Continuity Check provides a basic test of connectivity from package connectors to each die pad and to each individual die in a
DDP. This feature is an extension of the legacy unlock cycle sequence used at the beginning of several commands. The unlock
sequence is two writes with alternating ones and zeros pattern on the lower portion of the address and data lines with the pattern
inverted between the first and second write. To perform a continuity check these patterns are extended to cover all address (Amax
to 0) and data lines (DQ15 to 0). A logic comparison circuit looks for the alternating one and zero pattern that is inverted between the
two write cycles.
In the case of a DDP the A26 input is used to select which die the writes are sent to. When the correct patterns are detected the
status register bit zero is set to one. The status register clear command will clear the status register bit zero to a zero.
The following table describes the continuity check sequence for a single die (e.g. GL01GT) in x16.

Status Monitoring
There are three methods for monitoring EA status. Previous generations of the S29GL flash family used the methods called Data
Polling and Ready/Busy# (RY/BY#) Signal. These methods are still supported by the S29GL-T family. One additional method is
reading the Status Register.
5.5.1
Status Register
The status of program and erase operations is provided by a single 16-bit status register. The Status Register Read command is
written followed by a read access of the status register information. When the Status Register read command is issued, the current
status is captured (by the rising edge of WE#) into the register and the ASO is entered. The contents of the status register is aliased
(overlaid) the full memory address space. Valid read (CE# and OE# low) access in the Status Register ASO exits the ASO (with the
rising edge of CE# or OE# for tCEPH OEPH time) and returns to the address space map in use when the Status Register Read
/t
command was issued. While in x8 mode the full Status Register can be read (both the upper byte and lower byte) with one Status
Register entry by keeping CE# and OE# low and having a transition on A-1. Write operations are ignored and the device will stay in
Status Register ASO.The status register contains bits related to the results – success or failure – of the most recently completed
Embedded Algorithms (EA):
Erase Status (bit 5),
Program Status (bit 4),
Write Buffer Abort (bit 3),
Sector Locked Status (bit 1),
Continuity Check Pattern Detected (bit 0).
and, bits related to the current state of any in process EA:
Device Busy (bit 7),
Erase Suspended (bit 6),
Program Suspended (bit 2),
The current state bits indicate whether an EA is in process, suspended, or completed.
The upper 8 bits (bits 15:8) are reserved. These have undefined High or Low value that can change from one status read to another.
These bits should be treated as don't care and ignored by any software reading status.
The Soft Reset Command will clear to 0 bits [5, 4, 1, 0] of the status register if Status Register bit 3 =0. It will not affect the current
state bits.
The Clear Status Register Command will clear to 0 bits [5, 4, 3, 1, 0] of the status register but will not affect the current state bits.

Notes:
1. Bits 15 thru 8 are reserved for future use and may display as 0 or 1. These bits should be ignored (masked) when checking status.
2. Bit 7 is 1 when there is no Embedded Algorithm in progress in the device.
3. Bits 6 thru 1 are valid only if Bit 7 is 1.
4. All bits are put in their reset status by cold reset or warm reset.
5. Bits 5, 4, 3, and 1 are cleared to 0 by the Clear Status Register command or Reset command.
6. Upon issuing the Erase Suspend Command, the user must continue to read status until DRB becomes 1.
7. ESSB is cleared to 0 by the Erase Resume Command.
8. ESB reflects success or failure of the most recent erase operation.
9. PSB reflects success or failure of the most recent program operation.
10.During erase suspend, programming to the suspended sector or a sector in the queue, will be ignored and no error reported.
11. Upon issuing the Program Suspend Command, the user must continue to read status until DRB becomes 1.
12.PSSB is cleared to 0 by the Program Resume Command.
13.SLSB indicates that a program or erase operation failed because the sector was locked.
14. SLSB reflects the status of the most recent program or erase operation.
5.5.2
Data Polling Status
During an active Embedded Algorithm the EAC switches to the Data Polling ASO to display EA status to any read access. A single
word of status information is aliased in all locations of the device address space. In the status word there are several bits to
determine the status of an EA. These are referred to as DQ bits as they appear on the data bus during a read access while an EA is
in progress. DQ bits 15 to 8, DQ4, and DQ0 are reserved and provide undefined data. Status monitoring software must mask the
reserved bits and treat them as don't care. In X8 mode A-1 is ignored when performing Data Polling. Table 5.6 on page 40 and the
following subsections describe the functions of the remaining bits.
5.5.2.1
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Algorithm is in progress or has completed. Data#
Polling is valid after the rising edge of the final WE# pulse in the program or erase command sequence. Note that the Data# Polling
is valid only for the last word being programmed in the write-buffer-page during Write Buffer Programming. Reading Data# Polling
status on any word other than the last word to be programmed in the write-buffer-page will return false status information.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the data bit programmed to DQ7. This DQ7
status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs
the data bit programmed to bit 7 of the last word programmed. In case of a Program Suspend, the device allows only reading array
data. If a program address falls within a protected sector, Data# Polling on DQ7 is active for tDP, then the device returns to reading
array data.
During the Embedded Erase, Evaluate Erase Status, or Blank Check algorithms, Data# Polling produces a 0 on DQ7. When the
algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7. This is analogous to the
complement / true datum output described for the Embedded Program algorithm: the erase function changes all the bits in a sector
to 1; prior to this, the device outputs the complement or '0'. The system must provide an address within the sector selected for
erasure to read valid status information on DQ7.
Document Number: 002-00247 Rev. *G
Page 37 of 105
S29GL01GT, S29GL512T
After an erase command sequence is written, if the sector selected for erasing is protected, Data# Polling on DQ7 is active for tDP
,
then the device returns to reading array data.
Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ6-DQ0 while
Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7.
Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the
program or erase operation and DQ7 has valid data, the data outputs on DQ6-DQ0 may be still invalid. Valid data on DQ7-D00
appears on successive read cycles.
When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ15-DQ0 (Dq7-DQ0 in x8
mode) on the following read cycles. This is because DQ7 may change asynchronously with DQ6-DQ0 while Output Enable (OE#) is
asserted Low. This is illustrated in Figure 11.17 on page 87. Table 5.6 on page 40 shows the outputs for Data# polling on DQ7.
Figure 5.2 on page 24 shows the Data# polling algorithm use in Write Buffer Programming.
Valid DQ7 data polling status may only be read from:
the address of the last word loaded into the Write Buffer for a Write Buffer programming operation;
the location of a single word programming operation;
a location in a sector being erased, or evaluate erase status, or blank checked;
or a location in any sector during chip erase.

Note:
1. DQ7 should be rechecked even if DQ5 = 1 because DQ7 may change simultaneously with DQ5.
5.5.2.2
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device
has entered the Program Suspend or Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising
edge of the final WE# pulse in the command sequence (prior to the program or erase operation).
During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. (The
system may use either OE# or CE# to control the read cycles). When the operation is complete, DQ6 stops toggling.
After an erase command sequence is written, if the sector selected for erasing is protected, DQ6 toggles for tDP, then the EAC
returns to standby (Read Mode). If the selected sector is not protected, the Embedded Erase algorithm erases the unprotected
sector.
The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or erase-suspended. When the device
is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Program
Document Number: 002-00247 Rev. *G
Page 38 of 105
S29GL01GT, S29GL512T
Suspend mode or Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors
are erasing, or erase-suspended. Alternatively, the system can use DQ7 (see DQ7: Data# Polling on page 37).
DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete.
Table 5.6 on page 40 shows the outputs for Toggle Bit I on DQ6. Figure 5.6 on page 40 shows the toggle bit algorithm in flowchart
form, and the Reading Toggle Bits DQ6/DQ2 on page 39 explains the algorithm. Figure 5.6 on page 40 shows the toggle bit timing
diagrams. See also DQ2: Toggle Bit II on page 39.
5.5.2.3
DQ3: Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure has begun. See
Sector Erase on page 30 for more details. (The sector erase timer does not apply to the chip erase command.) If additional sectors
are selected for erasure, the entire time-out also applies after each additional sector erase command. When the time-out period is
complete, DQ3 switches from a 0 to a 1. If the time between additional sector erase commands from the system can be assumed to
be less than tSEA, then the system need not monitor DQ3.
After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure
that the device has accepted the command sequence, and then read DQ3. If DQ3 is 1, the Embedded Erase algorithm has begun;
all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is 0, the device accepts
additional sector erase commands. To ensure the command has been accepted, the system software should check the status of
DQ3 prior to and following each sub-sequent sector erase command. If DQ3 is high on the second status check, the last command
might not have been accepted. Table 5.6 on page 40 shows the status of DQ3 relative to the other status bits.
5.5.2.4
DQ2: Toggle Bit II
Toggle Bit II on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase
algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse
in the command sequence.
DQ2 toggles when the system reads at addresses within the sector selected for erasure (or all sectors selected for erase operation
during multi-sector erase). (The system may use either OE# or CE# to control the read cycles). But DQ2 cannot distinguish whether
the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in
Erase Suspend, but cannot distinguish if the sector is selected for erasure. Thus, both status bits are required for sector and mode
information. Refer to Table 5.6 on page 40 to compare outputs for DQ2 and DQ6. Figure 5.5 on page 38 shows the toggle bit
algorithm in flowchart form, and the Reading Toggle Bits DQ6/DQ2 on page 39 explains the algorithm. See also Figure 5.6
on page 40 shows the toggle bit timing diagram.
5.5.2.5
Reading Toggle Bits DQ6/DQ2
Refer to Figure 5.5 on page 38 for the following discussion. Whenever the system initially begins reading toggle bit status, it must
read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the
value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the
previous value. If the toggle bit is not toggling, the device has completed the program or erases operation. The system can read
array data on DQ15-DQ0 (DQ7-DQ0 in x8 mode) on the following read cycle.
However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note
whether the value of DQ5 is High (see DQ5: Exceeded Timing Limits on page 40). If it is, the system should then determine again
whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went High. If the toggle bit is no longer
toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not complete the
operation successfully, and the system must write the reset command to return to reading array data. It is recommended that data
read for polling purposes only be used for polling purposes. Once toggling has stopped array data will be available on subsequent
reads.
The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone High. The system
may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous
paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the
algorithm when it returns to determine the status of the operation (top of Figure 5.6 on page 40).

DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5
produces a 1. This is a failure condition that indicates the program or erase cycle was not successfully completed. The system must
issue the reset command to return the device to reading array data.
When a timeout occurs, the software must send a Soft Reset or Status Register Reset command to clear the timeout bit (DQ5) and
to return the EAC to the initial state. In this case, it is possible that the flash will continue to communicate busy for up to tTOR after the
reset command is sent.
5.5.2.7
DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a 1. The system must issue
the Write-to-Buffer-Abort-Reset command sequence or Status Register Clear command to return the EAC to standby (Read Mode)
and the Status Register failed bits are cleared. See Write Buffer Programming on page 23 for more details.

Notes:
1. DQ5 switches to '1' when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. See DQ5: Exceeded Timing Limits
on page 40 for more information.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. Data are invalid for addresses in a Program Suspended Line. All addresses other than the Program Suspended Line can be read for valid data.
4. DQ1 indicates the Write-to-Buffer ABORT status during Write-Buffer-Programming operations.
5. DQ3 = 0 for 50 µs after last sector is loaded during a multi-sector erase.
6. Applies only to program operations.
7. If SECSI is over laid on a suspended sector, if a program operation is initiated while in the SECSI mode, DQ6 will toggle and DQ2 will not toggle during the embedded
operation.
5.6
Error Types and Clearing Procedures
There are three types of errors reported by the embedded operation status methods. Depending on the error type, the status
reported and procedure for clearing the error status is different. Following is the clearing of error status:
If an ASO was entered before the error the device remains entered in the ASO awaiting ASO read or a command write.
If an erase was suspended before the error the device returns to the erase suspended state awaiting flash array read or a
command write.
Otherwise, the device will be in standby state awaiting flash array read or a command write.
5.6.1
Embedded Operation Error
If an error occurs during an embedded operation (program, erase, blank check, or password unlock) the device (EAC) remains busy.
The RY/BY# output remains Low, data polling status continues to be overlaid on all address locations, and the status register shows
ready with valid status bits. The device remains busy until the error status is detected by the host system status monitoring and the
error status is cleared.
During embedded algorithm error status the Data Polling status will show the following:
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer or last word of the password in the case of the
password unlock command. DQ7 = 0 for an erase, evaluate erase status, blank check failure
DQ6 continues to toggle
DQ5 = 1; Failure of the embedded operation
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 = 1 to indicate an embedded sector erase was in progress or 0 to indicate an embedded program was in progress
DQ2 continues to toggle, independent of the address used to read status
DQ1 = 0; Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
Document Number: 002-00247 Rev. *G
Page 41 of 105
S29GL01GT, S29GL512T
During embedded algorithm error status the Status Register will show the following:
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended during the EA error
SR[5] = 1 on erase or blank check error; else = 0
SR[4] = 1 on program or password unlock error; else = 0
SR[3] = 0; Write buffer abort
SR[2] = 0; Program suspended
SR[1] = 0; Protected sector
SR[0] = X; RFU, treat as don’t care (masked)
When the embedded algorithm error status is detected, it is necessary to clear the error status in order to return to normal operation,
with RY/BY# High, ready for a new read or command write. The error status can be cleared by writing:
Reset command
Status Register Clear command
Commands that are accepted during embedded algorithm error status are:
Status Register Read
Reset command
Status Register Clear command
5.6.2
Protection Error
If an embedded algorithm attempts to change data within a protected area (program, or erase of a protected sector or OTP area) the
device (EAC) goes busy for a period of tDP then returns to normal operation. During the busy period the RY/BY# output remains
Low, data polling status continues to be overlaid on all address locations, and the status register shows not ready with invalid status
bits (SR[7] = 0).
During the protection error status busy period the data polling status will show the following:
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer. DQ7 = 0 for an erase failure
DQ6 continues to toggle, independent of the address used to read status
DQ5 = 0; to indicate no failure of the embedded operation during the busy period
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 = 1 to indicate embedded sector erase in progress
DQ2 continues to toggle, independent of the address used to read status
DQ1 = 0; Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
Commands that are accepted during the protection error status busy period are:
Status Register Read
When the busy period ends the device returns to normal operation, the data polling status is no longer overlaid, RY/BY# is High, and
the status register shows ready with valid status bits. The device is ready for flash array read or write of a new command.
After the protection error status busy period the Status Register will show the following:
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended after the protection error busy period
SR[5] = 1 on erase error, else = 0
SR[4] = 1 on program error, else = 0
Document Number: 002-00247 Rev. *G
Page 42 of 105
S29GL01GT, S29GL512T
SR[3] = 0; Program not aborted
SR[2] = 0; No Program in suspension
SR[1] = 1; Error due to attempting to change a protected location
SR[0] = X; RFU, treat as don’t care (masked)
Commands that are accepted after the protection error status busy period are:
Any command
5.6.3
Write Buffer Abort
If an error occurs during a Write to Buffer command the device (EAC) remains busy. The RY/BY# output remains Low, data polling
status continues to be overlaid on all address locations, and the status register shows ready with valid status bits. The device
remains busy until the error status is detected by the host system status monitoring and the error status is cleared.
During write to buffer abort (WBA) error status the Data Polling status will show the following:
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer
DQ6 continues to toggle, independent of the address used to read status
DQ5 = 0; to indicate no failure of the programming operation. WBA is an error in the values input by the Write to Buffer command
before the programming operation can begin
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 is don't care after program operation as no erase is in progress. If the Write Buffer Program operation was started after an
erase operation had been suspended then DQ3 = 1. If there was no erase operation in progress then DQ3 is a don't care and
should be masked.
DQ2 does not toggle after program operation as no erase is in progress. If the Write Buffer Program operation was started after
an erase operation had been suspended then DQ2 will toggle in the sector where the erase operation was suspended and not in
any other sector. If there was no erase operation in progress then DQ2 is a don't care and should be masked.
DQ1 = 1: Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
During write to buffer abort (WBA) error status the Status Register will show the following:
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended during the WBA error status
SR[5] = 0; Erase successful
SR[4] = 1; Programming related error
SR[3] = 1; Write buffer abort
SR[2] = 0; No Program in suspension
SR[1] = 0; Sector not locked during operation
SR[0] = X; RFU, treat as don’t care (masked)
When the WBA error status is detected, it is necessary to clear the error status in order to return to normal operation, with RY/BY#
High, ready for a new read or command write. The error status can be cleared and device returned to normal operation by writing:
Write Buffer Abort Reset command
Status Register Clear command
Commands that are accepted during write to buffer abort (WBA) error status are:
Status Register Read
– Reads the status register and returns to WBA busy state
Write Buffer Abort Reset command
Status Register Clear command

Embedded Algorithm Performance Table
The Joint Electron Device Engineering Council (JEDEC) standard JESD22-A117 defines the procedural requirements for performing
valid endurance and retention tests based on a qualification specification. This methodology is intended to determine the ability of a
flash device to sustain repeated data changes without failure (program/erase endurance) and to retain data for the expected life
(data retention). Endurance and retention qualification specifications are specified in JESD47 or may be developed using
knowledge-based methods as in JESD94.

Legend:
X = Don't care.
RA = Address of the memory to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed.
PD = Data to be programmed at location PA.
SA = Address of the sector selected. Address bits Amax-A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same Line.
WC = Word Count is the number of write buffer locations to load minus 1.
PWAx = PPB Password address for word0 = 00h, word1 = 01h, word2 = 02h, and word3 = 03h. SSR3 Password address for word0 = 10h, word1
= 11h, word2 = 12h, and word3 = 13h.
PWDx = Password data word0, word1, word2, and word3.
Gray vs. White Box = Read vs. Write Operation.
Notes:
1. See Table 9.1, Interface States on page 62 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the following, all bus cycles are write cycle: read cycle during Read, ID/CFI Read (Manufacturing ID / Device ID), Indicator Bits,
Secure Silicon Region Read, SSR Lock Read, and 2nd cycle of Status Register Read.
4. Data bits DQ15-DQ8 are don't care in command sequences, except for RD, PD, WC and PWD.
5. Address bits Amax-A11 are don't cares for unlock and command cycles, unless SA or PA required. (Amax is the Highest Address pin.).
6. No unlock or command cycles required when reading array data.
7. The Reset command is required to return to reading array data when device is in the ASO mode, or if DQ5 goes High (while the device is
providing status data).
8. Command is valid when device is ready to read array data.
9. The Unlock-Bypass command is required prior to the Unlock-Bypass-Program and the unlock bypass write to buffer commands.
10. The Unlock-Bypass-Reset command is required to return to reading array data when the device is in the unlock bypass mode.
11. The system can read and program/program suspend in non-erasing sectors, or enter the ID-CFI ASO, when in the Erase Suspend mode. The
Erase Suspend command is valid only during a sector erase operation.
Document Number: 002-00247 Rev. *G
Page 50 of 105
S29GL01GT, S29GL512T
12. The Erase Resume/Program Resume command is valid only during the Erase Suspend/Program Suspend modes.
13. Issue this command sequence to return to Read State after detecting device is in a Write-to-Buffer-Abort state. IMPORTANT: the full command
sequence is required if resetting out of ABORT.
14.The Exit command returns the device to reading the array.
15. The password portion can be entered or read in any order as long as the entire 64-bit password is entered or read. Addresses are
10h-13h if the SSR3 is being accessed.
16. For PWDx, only one portion of the password can be programmed per each A0 command. Portions of the password must be programmed in
sequential order (PWD0 - PWD3).
17. All Lock Register bits are one-time programmable. The program state = 0 and the erase state = 1. Also, both the Persistent Protection Mode
Lock Bit and the Password Protection Mode Lock Bit cannot be programmed at the same time or the Lock Register Bits Program operation
halts and returns the device to Read State. Lock Register bits that are reserved for future use are undefined and may be 0’s or 1's.
18.If any of the Entry commands was issued, an Exit command must be issued to reset the device into Read State.
19. Protected State = 00h, Unprotected State = 01h. The sector address for DYB set, DYB clear, or PPB Program command may be any location
within the sector - the lower order bits of the sector address are don't care.
20.See Section 5.4.7.2, Sector Erase on page 30 for description of Multi-Sector Erase.

7.2
Device ID and Common Flash Interface (ID-CFI) ASO Map
The Device ID portion of the ASO (word locations 0h to 0Fh) provides manufacturer ID, device ID, Sector Protection State, and basic
feature set information for the device.
The access time to read location 02h is always tACC and a read of this location requires CE# to go High before the read and return
Low to initiate the read (asynchronous read access). Page mode read between location 02h and other ID locations is not supported.
Page mode read between ID locations other than 02h is supported.
In x8 mode, address A-1 is ignored and the lower 8 bits of data will be returned for both address, in CFI only. While in x8 only CFI or
only Autoselect data can be read. In x16 mode, able to read both memories from either command.
For additional information see ID-CFI ASO on page 32.

Word/Byte Configuration
The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE# pin is set at logic 1,
the device is in word configuration, DQ0-DQ15 are active and controlled by CE# and OE#.
If the BYTE# pin is set at logic 0, the device is in byte configuration, and only data I/O pins DQ0-DQ7 are active and controlled by
CE# and OE#. The data I/O pins DQ8-DQ14 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function.
The BYTE# pin can only be switch while the device is in standby (read mode).
The BYTE# pin has an internal pull-up. Though not required in a x16 only system, the pin should be connected to high (e.g. VIO)
8.4
Versatile I/O Feature
The maximum output voltage level driven by, and input levels acceptable to, the device are determined by the VIO power supply.
This supply allows the device to drive and receive signals to and from other devices on the same bus having interface signal levels
different from the device core voltage.
8.5
Ready/Busy# (RY/BY#)
RY/BY# is a dedicated, open drain output pin that indicates whether an Embedded Algorithm, Power-On Reset (POR), or Hardware
Reset is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in a command sequence,
when VCC is above VCC minimum during POR, or after the falling edge of RESET#. Since RY/BY# is an open drain output, several
RY/BY# pins can be tied together in parallel with a pull up resistor to VIO.
If the output is Low (Busy), the device is actively erasing, programming, or resetting. (This includes programming in the Erase
Suspend mode). If the output is High (Ready), the device is ready to read data (including during the Erase Suspend mode), or is in
the standby mode.
Table 5.6, Data Polling Status on page 40 shows the outputs for RY/BY# in each operation.
If an Embedded algorithm has failed (Program / Erase failure as result of max pulses or Program Abort),
RY/BY# will stay Low (busy) until status register bits 4 and 5 are cleared and the reset command is issued. If an Embedded
algorithm has failed (Sector is locked), RY/BY# will return High (ready). This includes Erase or Programming on a locked sector.
8.6
Hardware Reset
The RESET# input provides a hardware method of resetting the device to standby state. When RESET# is driven Low for at least a
period of tRP, the device immediately:
terminates any operation in progress,
exits any ASO,
tristates all outputs,
resets the Status Register,
resets the EAC to standby state.
CE# is ignored for the duration of the reset operation (tRPH).
To meet the Reset current specification (ICC5) CE# must be held High.
To ensure data integrity any operation that was interrupted should be reinitiated once the device is ready to accept another
command sequence.

9.2
Power-Off with Hardware Data Protection
The memory is considered to be powered off when the core power supply (VCC) drops below the lock-out voltage (VLKO). When VCC
is below VLKO, the entire memory array is protected against a program or erase operation. This ensures that no spurious alteration
of the memory content can occur during power transition. During a power supply transition down to Power-Off, VIO should remain
less than or equal to VCC
.
If VCC goes below VRST (Min) then returns above VRST (Min) to VCC minimum, the Power-On Reset interface state is entered and
the EAC starts the Cold Reset Embedded Algorithm.
9.3
Power Conservation Modes
Interface Standby
9.3.1
Standby is the default, low power, state for the interface while the device is not selected by the host for data transfer (CE# = High).
All inputs are ignored in this state and all outputs except RY/BY# are high impedance. RY/BY# is a direct output of the EAC, not
controlled by the Host Interface.
9.3.2
Automatic Sleep
The automatic sleep mode reduces device interface energy consumption to the sleep level (ICC6) following the completion of a
random read access time. The device automatically enables this mode when addresses remain stable for tACC + 30 ns. While in
automatic sleep mode, output data is latched and always available to the system. Output of the data depends on the level of the OE#
signal but, the automatic sleep mode current is independent of the OE# signal level. Standard address access timings (tACC or
tPACC) provide new data when addresses are changed. Refer the DC Characteristics on page 68 for the automatic sleep mode
current specification ICC6
.
Automatic sleep helps reduce current consumption especially when the host system clock is slowed for power reduction. During
slow system clock periods, read and write cycles may extend many times their length versus when the system is operating at high
speed. Even though CE# may be Low throughout these extended data transfer cycles, the memory device host interface will go to
the Automatic Sleep current at tACC + 30 ns. The device will remain at the Automatic Sleep current for tASSB. Then the device will
transition to the standby current level. This keeps the memory at the Automatic Sleep or standby power level for most of the long
duration data transfer cycles, rather than consuming full read power all the time that the memory device is selected by the host
system.
However, the EAC operates independent of the automatic sleep mode of the host interface and will continue to draw current during
an active Embedded Algorithm. Only when both the host interface and EAC are in their standby states is the standby level current
achieved.
9.4
Read
9.4.1
Read With Output Disable
When the CE# signal is asserted Low, the host system memory controller begins a read or write data transfer. Often there is a period
at the beginning of a data transfer when CE# is Low, Address is valid, OE# is High, and WE# is High. During this state a read access
is assumed and the Random Read process is started while the data outputs remain at high impedance. If the OE# signal goes Low,
the interface transitions to the Random Read state, with data outputs actively driven. If the WE# signal is asserted Low, the interface
transitions to the Write state. Note, OE# and WE# should never be Low at the same time to ensure no data bus contention between
the host system and memory.
9.4.2
Random (Asynchronous) Read
When the host system interface selects the memory device by driving CE# Low, the device interface leaves the Standby state. If
WE# is High when CE# goes Low, a random read access is started. The data output depends on the address map mode and the
address provided at the time the read access is started.
Document Number: 002-00247 Rev. *G
Page 63 of 105
S29GL01GT, S29GL512T
The data appears on DQ15-DQ0 (DQ7-DQ0 in x8 mode) when CE# is Low, OE# is Low, WE# remains High, address remains
stable, and the asynchronous access times are satisfied. Address access time (tACC) is equal to the delay from stable addresses to
valid output data. The chip enable access time (tCE) is the delay from stable CE# to valid data at the outputs. In order for the read
data to be driven on to the data outputs the OE# signal must be Low at least the output enable time (tOE) before valid data is
available.
At the completion of the random access time from CE# active (tCE), address stable (tACC), or OE# active (tOE), whichever occurs
latest, the data outputs will provide valid read data from the currently active address map mode. If CE# remains Low and any of the
Amax to A4 address signals change to a new value, a new random read access begins. If CE# remains Low and OE# goes High the
interface transitions to the Read with Output Disable state. If CE# remains Low, OE# goes High, and WE# goes Low, the interface
transitions to the Write state. If CE# returns High, the interface goes to the Standby state. Back to Back accesses, in which CE#
remains Low between accesses, requires an address change to initiate the second access. See Asynchronous Read Operations
on page 75.
9.4.3
Page Read
After a Random Read access is completed, if CE# remains Low, OE# remains Low, the Amax to A4 address signals remain stable,
and any of the A3 to A0 address signals change, a new access within the same Page begins. In x8 mode, when any of the A3 to A-
1 address signals change, a new access within the same Page begins. The Page Read completes much faster (tPACC) than a
Random Read access.
9.5
Write
9.5.1
Asynchronous Write
When WE# goes Low after CE is Low, there is a transition from one of the read states to the Write state. If WE# is Low before CE#
goes Low, there is a transition from the Standby state directly to the Write state without beginning a read access.
When CE# is Low, OE# is High, and WE# goes Low, a write data transfer begins. Note, OE# and WE# should never be Low at the
same time to ensure no data bus contention between the host system and memory. When the asynchronous write cycle timing
requirements are met the WE# can go High to capture the address and data values in to EAC command memory.
Address is captured by the falling edge of WE# or CE#, whichever occurs later. Data is captured by the rising edge of WE# or CE#,
whichever occurs earlier.
When CE# is Low before WE# goes Low and stays Low after WE# goes High, the access is called a WE# controlled Write. When
WE# is High and CE# goes High, there is a transition to the Standby state. If CE# remains Low and WE# goes High, there is a
transition to the Read with Output Disable state.
When WE# is Low before CE# goes Low and remains Low after CE# goes High, the access is called a CE# controlled Write. A CE#
controlled Write transitions to the Standby state.
If WE# is Low before CE# goes Low, the write transfer is started by CE# going Low. If WE# is Low after CE# goes High, the address
and data are captured by the rising edge of CE#. These cases are referred to as CE# controlled write state transitions.
Write followed by Read accesses, in which CE# remains Low between accesses, requires an address change to initiate the
following read access.
Back to Back accesses, in which CE# remains Low between accesses, requires an address change to initiate the second access.
The EAC command memory array is not readable by the host system and has no ASO. The EAC examines the address and data in
each write transfer to determine if the write is part of a legal command sequence. When a legal command sequence is complete the
EAC will initiate the appropriate EA.
9.5.2
Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on WE# will not initiate a write cycle.
9.5.3
Logical Inhibit
Write cycles are inhibited by holding OE# at VIL, or CE# at VIH, or WE# at VIH. To initiate a write cycle, CE# and WE# must be Low
(VIL) while OE# is High (VIH).

Note:
1. Operating ranges define those limits between which the functionality of the device is guaranteed.
10.4.3 Power-Up and Power-Down
During power-up or power-down VCC must always be greater than or equal to VIO (VCC VIO).
The device ignores all inputs until a time delay of tVCS has elapsed after the moment that VCC and VIO both rise above, and stay
above, the minimum VCC and VIO thresholds. During tVCS the device is performing power on reset operations.
During power-down or voltage drops below VCC Lockout maximum (VLKO), the VCC and VIO voltages must drop below VCC Reset
(VRST) minimum for a period of tPD for the part to initialize correctly when VCC and VIO again rise to their operating ranges. See
Figure 10.2 on page 67. If during a voltage drop the VCC stays above VLKO maximum the part will stay initialized and will work
correctly when VCC is again above VCC minimum. If the part locks up from improper initialization, a hardware reset can be used to
initialize the part correctly.
Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each device in a system
should have the VCC and VIO power supplies decoupled by a suitable capacitor close to the package connections (this capacitor is
generally on the order of 0.1 µF). At no time should VIO be greater then 200 mV above VCC (VCC VIO - 200 mV).

11.3 Power-On Reset (POR) and Warm Reset
Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each device in a system
should have the VCC and VIO power supplies decoupled by a suitable capacitor close to the package connections (this capacitor is
generally on the order of 0.1 µF).

11.3.1 Power-On (Cold) Reset (POR)
During the rise of power supplies the VIO supply voltage must remain less than or equal to the VCC supply voltage. VIH also must
remain less than or equal to the VIO supply.
The Cold Reset Embedded Algorithm requires a relatively long, hundreds of µs, period (tVCS) to load all of the EAC algorithms and
default state from non-volatile memory. During the Cold Reset period all control signals including CE# and RESET# are ignored. If
CE# is Low during tVCS the device may draw higher than normal POR current during tVCS but the level of CE# will not affect the Cold
Reset EA. RESET# may be High or Low during tVCS. If RESET# is Low during tVCS it may remain Low at the end of tVCS to hold the
device in the Hardware Reset state. If RESET# is High at the end of tVCS the device will go to the Standby state.
When power is first applied, with supply voltage below VRST then rising to reach operating range minimum, internal device
configuration and warm reset activities are initiated. CE# is ignored for the duration of the POR operation (tVCS or tVIOS). RESET#
Low during this POR period is optional. If RESET# is driven Low during POR it must satisfy the Hardware Reset parameters tRP and
tRPH. In which case the Reset operations will be completed at the later of tVCS or tVIOS or tRPH. A CE#, OE#, or Address transition
will initiate the 1st read operation. If CE# is held low during POR than the current address will be automatically read.
During Cold Reset the device will draw ICC7 current.

11.3.2 Hardware (Warm) Reset
During Hardware Reset (tRPH) the device will draw ICC5 current.
When RESET# continues to be held at VSS, the device draws CMOS standby current (ICC4). If RESET# is held at VIL, but not at VSS
the standby current is greater.
,
If a Cold Reset has not been completed by the device when RESET# is asserted Low after tVCS, the Cold Reset# EA will be
performed instead of the Warm RESET#, requiring tVCS time to complete. See Figure 11.4, Hardware Reset on page 74.
After the device has completed POR and entered the Standby state, any later transition to the Hardware Reset state will initiate the
Warm Reset Embedded Algorithm. A Warm Reset is much shorter than a Cold Reset, taking tens of µs (tRPH) to complete. During
the Warm Reset EA, any in progress Embedded Algorithm is stopped and the EAC is returned to its POR state without reloading
EAC algorithms from non-volatile memory. After the Warm Reset EA completes, the interface will remain in the Hardware Reset
state if RESET# remains Low. When RESET# returns High the interface will transit to the Standby state. If RESET# is High at the
end of the Warm Reset EA, the interface will directly transit to the Standby state. If CE# is held low during Warm Reset than the
current address will be automatically read.
If POR has not been properly completed by the end of tVCS, a later transition to the Hardware Reset state will cause a transition to
the Power-on Reset interface state and initiate the Cold Reset Embedded Algorithm. This ensures the device can complete a Cold
Reset even if some aspect of the system Power-On voltage ramp-up causes the POR to not initiate or complete correctly. The RY/
BY# pin is Low during cold or warm reset as an indication that the device is busy performing reset operations.
Hardware Reset is initiated by the RESET# signal going to VIL.

Valid Combinations — Automotive Grade / AEC-Q100
The table below lists configurations that are Automotive Grade / AEC-Q100 qualified and are planned to be available in volume. The
table will be updated as new combinations are released. Consult your local sales representative to confirm availability of specific
combinations and to check on newly released combinations.
Production Part Approval Process (PPAP) support is only provided for AEC-Q100 grade products.
Products to be used in end-use applications that require ISO/TS-16949 compliance must be AEC-Q100 grade products in
combination with PPAP. Non–AEC-Q100 grade products are not manufactured or documented in full compliance with
ISO/TS-16949 requirements.
AEC-Q100 grade products are also offered without PPAP support for end-use applications that do not require ISO/TS-16949
compliance.
