Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

Functional Overview
The J3 65 nm SBC family contains high-density memory organized in any of the
following configurations:
• 16-MB or 8-MW (128-Mbit), organized as one-hundred-twenty-eight 128-KB erase
blocks.
• 8-MB or 4-MW (64-Mbit), organized as sixty-four 128-KB erase blocks.
• 4-MB or 2-MW (32-Mbit), organized as thirty-two 128-KB erase blocks.
These devices can be accessed as 8- or 16-bit words. See Figure 1, “Memory Block
Diagram for 32-, 64-, 128-Mbit” on page 11 for further details.
A 128-bit Protection Register has multiple uses, including unique flash device
identification.
The J3 65 nm SBC device includes new security features that were not available on the
(previous) 0.13µm versions of the J3 family. These new security features prevent
altering of code through different protection schemes that can be implemented, based
on user requirements.
The J3 65 nm SBC optimized architecture and interface dramatically increases read
performance by supporting page-mode reads. This read mode is ideal for non-clock
memory systems.
Its Common Flash Interface (CFI) permits software algorithms to be used for entire
families of devices. This allows device-independent, JEDEC ID-independent, and
forward- and backward-compatible software support for the specified flash device
families. Flash vendors can standardize their existing interfaces for long-term
compatibility.
The Scalable Command Set (SCS) allows a single, simple software driver in all host
systems to work with all SCS-compliant flash memory devices, independent of system-
level packaging (e.g., memory card, SIMM, or direct-to-board placement). Additionally,
SCS provides the highest system/device data transfer rates and minimizes device and
system-level implementation costs.
A Command User Interface (CUI) serves as the interface between the system processor
and internal operation of the device. A valid command sequence written to the CUI
initiates device automation. An internal Write State Machine (WSM) automatically
executes the algorithms and timings necessary for block erase, program, and lock-bit
configuration operations.
A block erase operation erases one of the device’s 128-KB blocks typically within one
second, independent of other blocks. Each block can be independently erased 100,000
times. Block erase suspend mode allows system software to suspend block erase to
read or program data from any other block. Similarly, program suspend allows system
software to suspend programming (byte/word program and write-to-buffer operations)
to read data or execute code from any other block that is not being suspended.
Each device incorporates a Write Buffer of 256-Byte (x8 mode) or 256-Word (x16
mode) to allow optimum programming performance. By using the Write Buffer data is
programmed more efficiently in buffer increments.
Memory Blocks are selectively and individually lockable in-system. Individual block
locking uses block lock-bits to lock and unlock blocks. Block lock-bits gate block erase
and program operations. Lock-bit configuration operations set and clear lock-bits (using
the Set Block Lock-Bit and Clear Block Lock-Bits commands).

The Status Register indicates when the WSM’s block erase, program, or lock-bit
configuration operation completes.
The STS (status) output gives an additional indicator of WSM activity by providing both
a hardware signal of status (versus software polling) and status masking (interrupt
masking for background block erase, for example). Status indication using STS
minimizes both CPU overhead and system power consumption. When configured in
level mode (default mode), it acts as a RY/BY# signal. When low, STS indicates that the
WSM is performing a block erase, program, or lock-bit configuration. STS-high indicates
that the WSM is ready for a new command, block erase is suspended (and
programming is inactive), program is suspended, or the device is in reset/power-down
mode. Additionally, the configuration command allows the STS signal to be configured
to pulse on completion of programming and/or block erases.
Three CE signals are used to enable and disable the device. A unique CE logic design
(see Table 17, “Chip Enable Truth Table for 32-, 64-, 128-Mb” on page 30) reduces
decoder logic typically required for multi-chip designs. External logic is not required
when designing a single chip, a dual chip, or a 4-chip miniature card or SIMM module.
The BYTE# signal allows either x8 or x16 read/writes to the device:
• BYTE#-low enables 8-bit mode; address A0 selects between the low byte and high
byte.
• BYTE#-high enables16-bit operation; address A1 becomes the lowest order
address and address A0 is not used (don’t care).
Figure 1, “Memory Block Diagram for 32-, 64-, 128-Mbit” on page 11 shows a device
block diagram.
When the device is disabled (see Table 17, “Chip Enable Truth Table for 32-, 64-, 128-
Mb” on page 30), with CEx at VIH and RP# at VIH, the standby mode is enabled. When
RP# is at VIL, a further power-down mode is enabled which minimizes power
consumption and provides write protection during reset. A reset time (tPHQV) is
required from RP# going high until data outputs are valid. Likewise, the device has a
wake time (tPHWL) from RP#-high until writes to the CUI are recognized. With RP# at
VIL, the WSM is reset and the Status Register is cleared.

Signal Descriptions
Table 3 lists the active signals used on J3 65 nm SBC and provides a description of
each.
Table 3:
Signal Descriptions for J3 65 nm SBC
Symbol
Type
Name and Function
BYTE-SELECT ADDRESS: Selects between high and low byte when the device is in x8 mode. This
address is latched during a x8 program cycle. Not used in x16 mode (i.e., the A0 input buffer is
turned off when BYTE# is high).
A0
Input
ADDRESS INPUTS: Inputs for addresses during read and program operations. Addresses are
internally latched during a program cycle:
32-Mbit — A[21:1]
64-Mbit— A[22:1]
128-Mbit — A[23:1]
A[MAX:1]
Input
LOW-BYTE DATA BUS: Inputs data during buffer writes and programming, and inputs commands
during CUI writes. Outputs array, CFI, identifier, or status data in the appropriate read mode. Data
is internally latched during write operations.
Input/
Output
DQ[7:0]
HIGH-BYTE DATA BUS: Inputs data during x16 buffer writes and programming operations.
Outputs array, CFI, or identifier data in the appropriate read mode; not used for Status Register
reads. Data is internally latched during write operations in x16 mode. D[15:8] float in x8 mode.
Input/
Output
DQ[15:8]
CHIP ENABLE: Activates the 32-, 64-, 128-Mbit devices’ control logic, input buffers, decoders, and
sense amplifiers. When the device is de-selected (see Table 17, “Chip Enable Truth Table
for 32-, 64-, 128-Mb” on page 30), power reduces to standby levels.
All timing specifications are the same for these three signals. Device selection occurs with the first
edge of CE0, CE1, or CE2 that enables the device. Device deselection occurs with the first edge of
CE0, CE1, or CE2 that disables the device (see Table 17, “Chip Enable Truth Table for
32-, 64-, 128-Mb” on page 30).
CE[2:0]
Input
RESET: RP#-low resets internal automation and puts the device in power-down mode. RP#-high
enables normal operation. Exit from reset sets the device to read array mode. When driven low,
RP# inhibits write operations which provides data protection during power transitions.
RP#
Input
OUTPUT ENABLE: Activates the device’s outputs through the data buffers during a read cycle.
OE# is active low.
OE#
WE#
Input
Input
WRITE ENABLE: Controls writes to the CUI, the Write Buffer, and array blocks. WE# is active low.
Addresses and data are latched on the rising edge of WE#.
STATUS: Indicates the status of the internal state machine. When configured in level mode
(default), it acts as a RY/BY# signal. When configured in one of its pulse modes, it can pulse to
indicate program and/or erase completion. For alternate configurations of the Status signal, see the
Configurations command and Section 9.7, “Status Signal” on page 41. STS is to be tied
to VCCQ with a pull-up resistor.
Open Drain
Output
STS
BYTE ENABLE: BYTE#-low places the device in x8 mode; data is input or output on D[7:0], while
D[15:8] is placed in High-Z. Address A0 selects between the high and low byte. BYTE#-high places
the device in x16 mode, and turns off the A0 input buffer, the address A1 becomes the lowest-order
address bit.

Power-Up/Down
This section provides an overview of system level considerations with regards to the
flash device. It includes a brief description of power-up/down sequence and decoupling
design considerations.
5.3.1
Power-Up/Down Sequence
To prevent conditions that could result in spurious program or erase operations, the
power-up/power-down sequence shown in Table 6 is recommended. For DC voltage
characteristics refer to Table 8. Note that each power supply must reach its minimum
voltage range before applying/removing the next supply voltage.

Note:

Power supplies connected or sequenced together.
Device inputs must not be driven until all supply voltages reach their minimum range.
RP# should be low during power transitions.
5.3.2
Power Supply Decoupling
When the device is enabled, many internal conditions change. Circuits are energized,
charge pumps are switched on, and internal voltage nodes are ramped. All of this
internal activities produce transient signals. The magnitude of the transient signals
depends on the device and system loading. To minimize the effect of these transient
signals, a 0.1 µF ceramic capacitor is required across each VCC/VSS and VCCQ signal.
Capacitors should be placed as close as possible to device connections.
Additionally, for every eight flash devices, a 4.7 µF electrolytic capacitor should be
placed between VCC and VSS at the power supply connection. This 4.7 µF capacitor
should help overcome voltage slumps caused by PCB trace inductance.
5.4
Reset
By holding the flash device in reset during power-up and power-down transitions,
invalid bus conditions may be masked. The flash device enters reset mode when RP# is
driven low. In reset, internal flash circuitry is disabled and outputs are placed in a high-
impedance state. After return from reset, a certain amount of time is required before
the flash device is able to perform normal operations. After return from reset, the flash
device defaults to asynchronous page mode. If RP# is driven low during a program or
erase operation, the program or erase operation will be aborted and the memory
contents at the aborted block or address are no longer valid. See Figure 12, “AC
Waveform for Reset Operation” on page 28 for detailed information regarding reset
timings.

A write operation can be initiated and terminated with either CEX or WE#.
Sampled, not 100% tested.
Write pulse width (tWP) is defined from CEX or WE# going low (whichever goes low last) to CEX or WE# going high
(whichever goes high first). Hence, tWP = tWLWH = tELEH = tWLEH = tELWH
.

Refer to Table 18, “Enhanced Configuration Register” on page 32 for valid AIN and DIN for block erase,
program, or lock-bit configuration.
Write pulse width high (tWPH) is defined from CEX or WE# going high (whichever goes high first) to CEX or WE# going
low (whichever goes low first). Hence, tWPH = tWHWL = tEHEL = tWHEL = tEHWL
.

Bus Interface
This section provides an overview of Bus operations. The on-chip Write State Machine
(WSM) manages all erase and program algorithms. The system CPU provides control of
all in-system read, write, and erase operations through the system bus. All bus cycles
to or from the flash memory conform to standard microprocessor bus cycles. Table 16
summarizes the necessary states of each control signal for different modes of
operations.

OE# and WE# should never be asserted simultaneously. If done so, OE# overrides WE#.
DQ refers to DQ[7:0] when BYTE# is low and DQ[15:0] if BYTE# is high.
Refer to DC characteristics. When VPEN ≤ VPENLK, memory contents can be read but not altered.
X should be VIL or VIH for the control pins and VPENLK or VPENH for VPEN. For outputs, X should be VOL or VOH
.
In default mode, STS is VOL when the WSM is executing internal block erase, program, or a lock-bit configuration
algorithm. It is VOH (pulled up by an external pull up resistance ≈ 10k) when the WSM is not busy, in block erase suspend
mode (with programming inactive), program suspend mode, or reset power-down mode.

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)
8.1
Bus Reads
Reading from flash memory outputs stored information to the processor or chipset, and
does not change any contents. Reading can be performed an unlimited number of
times. Besides array data, other types of data such as device information and device
status are available from the flash.
To perform a bus read operation, CEx (refer to Table 17 on page 30) and OE# must be
asserted. CEx is the device-select control; when active, it enables the flash memory
device. OE# is the data-output control; when active, the addressed flash memory data
is driven onto the I/O bus. For all read states, WE# and RP# must be de-asserted. See
Section 9.2, “Read Operations” on page 35.
8.1.1
Asynchronous Page Mode Read
Unlike J3 130nm devices, J3 65 nm SBC device provides Eight-Word Asynchronous
Page mode only. Array data can be sensed up to eight words (16 Bytes) at a time. This
is the default mode on power-up or reset.
On J3 130nm devices, the Set Enhanced Configuration Register command is used to
enable Eight-Word Page mode upon power-up or reset, however this has no effect on J3
65 nm SBC device anymore.
After the initial access delay, the first word out of the page buffer corresponds to the
initial address. Address bits A[3:1] determine which word is output from the page
buffer for a x16 bus width, and A[3:0] determine which byte is output from the page
buffer for a x8 bus width. Subsequent reads from the device come from the page
buffer. These reads are output on DQ[15:0] for a x16 bus width and DQ[7:0] for a x8
bus width after a minimum delay by changing A[3:1] or A[3:0].
Data can be read from the page buffer multiple times, and in any order.If address bits
A[MAX:4] change at any time, or if CEx# is toggled, the device will sense and load new
data into the page buffer. Asynchronous Page mode is the default read mode on power-
up or reset.
To perform a Page mode read after any other operation, the Read Array command must
be issued to read from the flash array. Asynchronous Page mode reads are permitted in
all blocks and are used to access register information. During register access, only one
word is loaded into the page buffer.
8.1.1.1
Enhanced Configuration Register
The Enhanced Configuration Register (ECR) is a volatile storage register that when
addressed by the Set ECR command can select between Four-Word Page mode and
Eight-Word Page mode on J3 130nm devices, however this has no effect on J3 65 nm
SBC device.
The ECR is volatile; all bits will be reset to default values when RP# is deasserted or
power is removed from the device. To modify ECR settings, use the Set ECR command.
The Set ECR command is written along with the configuration register value, which is
placed on the lower 16 bits of the address bus A[16:1]. This is followed by a second
write that confirms the operation and again presents the ECR data on the address bus.
After executing this command, the device returns to Read Array mode.
The ECR is shown in Table 18. 8-word page mode Command Bus-Cycle is captured in
Table 19 for backward compatibility reasons.
Note:
If the 8-word Asynchronous Page mode is used on J3 65 nm SBC, a Clear Status
Register command must be executed after issuing the Set ECR command.

8.2
Bus Writes
Writing or Programming to the device, is where the host writes information or data into
the flash device for non-volatile storage. When the flash device is programmed, ‘ones’
are changed to ‘zeros’. ‘Zeros’ cannot be programed back to ‘ones’. To do so, an erase
operation must be performed. Writing commands to the Command User Interface (CUI)
enables various modes of operation, including the following:
• Reading of array data
• Common Flash Interface (CFI) data
• Identifier codes, inspection, and clearing of the Status Register
• Block Erasure, Program, and Lock-bit Configuration (when VPEN = VPENH
)
Erasing is performed on a block basis – all flash cells within a block are erased together.
Any information or data previously stored in the block will be lost. Erasing is typically
done prior to programming. The Block Erase command requires appropriate command
data and an address within the block to be erased. The Byte/Word Program command
requires the command and address of the location to be written. Set Block Lock-Bit
commands require the command and block within the device to be locked. The Clear
Block Lock-Bits command requires the command and address within the device to be
cleared.
The CUI does not occupy an addressable memory location. It is written when the device
is enabled and WE# is active. The address and data needed to execute a command are
latched on the rising edge of WE# or CEX (CEX low is defined as the combination of pins
CE0, CE1, and CE2 that enable the device. CEX high is defined as the combination of
pins CE0, CE1, and CE2 that disable the device. See Table 17 on page 30). Standard
microprocessor write timings are used.

8.3
Standby
CE0, CE1, and CE2 can disable the device (see Table 17 on page 30) and place it in
standby mode. This manipulation of CEx substantially reduces device power
consumption. DQ[15:0] outputs are placed in a high-impedance state independent of
OE#. If deselected during block erase, program, or lock-bit configuration, the WSM
continues functioning, and consuming active power until the operation completes.
8.3.1
Reset/Power-Down
RP# at VIL initiates the reset/power-down mode.
In read modes, RP#-low deselects the memory, places output drivers in a high-
impedance state, and turns off numerous internal circuits. RP# must be held low for a
minimum of tPLPH. Time tPHQV is required after return from reset mode until initial
memory access outputs are valid. After this wake-up interval, normal operation is
restored. The CUI is reset to read array mode and Status Register is set to 0080h.
During Block Erase, Program, or Lock-Bit Configuration modes, RP#-low will abort the
operation. In default mode, STS transitions low and remains low for a maximum time
of tPLPH + tPHRH until the reset operation is complete. Memory contents being altered
are no longer valid; the data may be partially corrupted after a program or partially
altered after an erase or lock-bit configuration. Time tPHWL is required after RP# goes to
logic-high (VIH) before another command can be written.
As with any automated device, it is important to assert RP# during system reset. When
the system comes out of reset, it expects to read from the flash memory. Automated
flash memories provide status information when accessed during Block Erase, Program,
or Lock-Bit Configuration modes. If a CPU reset occurs with no flash memory reset,
proper initialization may not occur because the flash memory may be providing status
information instead of array data. Numonyx Flash memories allow proper initialization
following a system reset through the use of the RP# input. In this application, RP# is
controlled by the same RESET# signal that resets the system CPU.
8.4
Device Commands
When VPEN ≤ VPENLK, only read operations from the Status Register, CFI, identifier
codes, or blocks are enabled. Placing VPENH on VPEN additionally enables block erase,
program, and lock-bit configuration operations. Device operations are selected by
writing specific commands to the Command User Interface (CUI). The CUI does not
occupy an addressable memory location. It is the mechanism through which the flash
device is controlled.
A command sequence is issued in two consecutive write cycles - a Setup command
followed by a Confirm command. However, some commands are single-cycle
commands consisting of a setup command only. Generally, commands that alter the
contents of the flash device, such as Program or Erase, require at least two write cycles
to guard against inadvertent changes to the flash device. Flash commands fall into two
categories: Basic Commands and Extended Commands. Basic commands are
recognized by all Numonyx Flash devices, and are used to perform common flash
operations such as selecting the read mode, programming the array, or erasing blocks.
Extended commands are product-dependant; they are used to perform additional
features such as software block locking. Section 11.0, “Device Command Codes” on
page 47 describes all applicable commands on J3 65 nm SBC device.

Flash Operations
This section describes the operational features of flash memory. Operations are
command-based, wherein command codes are first issued to the device, then the
device performs the desired operation. All command codes are issued to the device
using bus-write cycles (see Chapter 8.0, “Bus Interface”). A complete list of available
command codes can be found in Section 11.0, “Device Command Codes” on page 47.
9.1
Status Register
The Status Register (SR) is an 8-bit, read-only register that indicates device status and
operation errors. To read the Status Register, issue the Read Status Register command.
Subsequent reads output Status Register information on DQ[7:0], and 00h on
DQ[15:8].
SR status bits are set and cleared by the device. SR error bits are set by the device, but
must be cleared using the Clear Status Register command. Upon power-up or exit from
reset, the Status Register defaults to 80h. Page-mode reads are not supported in this
read mode. Status Register contents are latched on the falling edge of OE# or CEX (CEX
low is defined as the combination of pins CE0, CE1, and CE2 that enable the device.
CEX high is defined as the combination of pins CE0, CE1, and CE2 that disable the
device). OE# must toggle to VIH or the device must be disabled before further reads to
update the Status Register latch. The Read Status Register command functions
independently of VPEN voltage.

Clearing the Status Register
The Status Register (SR) contain Status and error bits which are set by the device. SR
status bits are cleared by the device, however SR error bits are cleared by issuing the
Clear SR command (see Table 21). Resetting the device also clears the SR.

Issuing the Clear SR command places the device in Read SR mode.
Note:
Care should be taken to avoid SR ambiguity. If a command sequence error occurs while
in an Erase Suspend condition, the SR will indicate a Command Sequence error by
setting SR.4 and SR.5. When the erase operation is resumed (and finishes), any errors
that may have occurred during the erase operation will be masked by the Command
Sequence error. To avoid this situation, clear the Status Register prior to resuming a
suspended erase operation. The Clear SR command functions independent of the
voltage level on VPEN.

Read Operations
Four types of data can be read from the device: array data, device information, CFI
data, and device status. Upon power-up or return from reset, the device defaults to
Read Array mode. To change the device’s read mode, the appropriate command must
be issued to the device. Table 22 shows the command codes used to configure the
device for the desired read mode. The following sections describe each read mode.

9.2.1
Read Array
Upon power-up or return from reset, the device defaults to Read Array mode. Issuing
the Read Array command places the device in Read Array mode. Subsequent reads
output array data on DQ[15:0]. The device remains in Read Array mode until a
different read command is issued, or a program or erase operation is performed, in
which case, the read mode is automatically changed to Read Status.
To change the device to Read Array mode while it is programming or erasing, first issue
the Suspend command. After the operation has been suspended, issue the Read Array
command. When the program or erase operation is subsequently resumed, the device
will automatically revert back to Read Status mode.
Note:
Issuing the Read Array command to the device while it is actively programming or
erasing causes subsequent reads from the device to output invalid data. Valid array
data is output only after the program or erase operation has finished.

The Read Array command functions independent of the voltage level on VPEN.
9.2.2
Read Status Register
Issuing the Read Status Register command places the device in Read Status Register
mode. Subsequent reads output Status Register information on DQ[7:0], and 00h on
DQ[15:8]. The device remains in Read Status Register mode until a different read-
mode command is issued. Performing a program, erase, or block-lock operation also
changes the device’s read mode to Read Status Register mode.
The Status Register is updated on the falling edge of OE# or CEx, whichever occurs
last. Status Register contents are valid only when SR.7 = 1. When WSM is active, SR.7
indicates the WSM’s state and SR[6:0] are in high-Z state.
The Read Status Register command functions independent of the voltage level on
VPEN.
9.2.3
Read Device Information
Issuing the Read Device Information command places the device in Read Device
Information mode. Subsequent reads output device information on DQ[15:0].
The device remains in Read Device Information mode until a different read command is
issued. Also, performing a program, erase, or block-lock operation changes the device
to Read Status Register mode.
The Read Device Information command functions independent of the voltage level on
VPEN.
9.2.4
CFI Query
The CFI query table contains an assortment of flash product information such as block
size, density, allowable command sets, electrical specifications, and other product
information. The data contained in this table conforms to the CFI protocol.
Issuing the CFI Query command places the device in CFI Query mode. Subsequent
reads output CFI information on DQ[15:0]. The device remains in CFI Query mode until
a different read command is issued, or a program or erase operation is performed,
which changes the read mode to Read Status Register mode.
The CFI Query command functions independent of the voltage level on VPEN.
9.3
Programming Operations
All programming operations require the addressed block to be unlocked, and a valid
VPEN voltage applied throughout the programming operation. Otherwise, the
programming operation will abort, setting the appropriate Status Register error bit(s).
The following sections describe each programming method.
9.3.1
Single-Word/Byte Programming
Array programming is performed by first issuing the Single-Word/Byte Program
command. This is followed by writing the desired data at the desired array address. The
read mode of the device is automatically changed to Read Status Register mode, which
remains in effect until another read-mode command is issued.

During programming, STS and the Status Register indicate a busy status (SR.7 = 0).
Upon completion, STS and the Status Register indicate a ready status (SR.7 = 1). The
Status Register should be checked for any errors (SR.4), then cleared.
Note:
Issuing the Read Array command to the device while it is actively programming causes
subsequent reads from the device to output invalid data. Valid array data is output only
after the program operation has finished.
Standby power levels are not be realized until the programming operation has finished.
Also, asserting RP# aborts the programming operation, and array contents at the
addressed location are indeterminate. The addressed block should be erased, and the
data re-programmed. If a Single-Word/Byte program is attempted when the
corresponding block lock-bit is set, SR.1 and SR.4 will be set.
9.3.2
Buffered Programming
Buffered programming operations simultaneously program multiple words/bytes into
the flash memory array, significantly reducing effective word-write/byte-write times.
User-data is first written to a write buffer, then programmed into the flash memory
array in buffer-size increments. For additional details, see the flow chart of the
buffered-programming operation.
Optimal performance and power consumption is realized by aligning the start address
on 256-Word boundaries (i.e., A[8:1] = 00000000b). Crossing a 256-Word boundary
during a buffered programming operation can cause programming time to double.
To perform a buffered programming operation, first issue the Buffered Program setup
command at the desired starting address. The read mode of the device/addressed
partition is automatically changed to Read Status Register mode.
Polling SR.7 determines write-buffer availability (0 = not available, 1 = available). If
the write buffer is not available, re-issue the setup command and check SR.7; repeat
until SR.7 = 1.
Note:
The device defaults to output SR data after the Buffered Programming Setup command
(E8h) is issued. CE# and OE# must be toggled to update Status Register. Don’t issue
the Read SR command (70h), which would be interpreted by the internal state machine
as Buffer Word Count.
Next, issue the word count at the desired starting address. The word count represents
the total number of words to be written into the write buffer, minus one. This value can
range from 00h (one) to a maximum of FFh (256). Exceeding the allowable range
causes an abort.
Note:
The maximum number of bytes in write buffer on CFI region (offset 2Ah, refer Table 41,
“Device Geometry Definition” on page 60) is set to 05h (32 bytes) for backward
compatible reasons. No software change is required on existing applications for both x8
and x16 mode. Applications can optimize the system performance using the maximum
of 256 buffer size. Please contact your sales representatives for questions.
Following the word count, the write buffer is filled with user-data. Subsequent bus-
write cycles provide addresses and data, up to the word count. All user-data addresses
must lie between <starting address> and <starting address + word count>, otherwise
the WSM continues to run as normal but, user may advertently change the content in
unexpected address locations.
Note:
User-data is programmed into the flash array at the address issued when filling the
write buffer.

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)
After all user-data is written into the write buffer, issue the confirm command. If a
command other than the confirm command is issued to the device, a command
sequence error occurs and the operation aborts.
Note:
After issuing the confirm command, write-buffer contents are programmed into the
flash memory array. The Status Register indicates a busy status (SR.7 = 0) during
array programming.Issuing the Read Array command to the device while it is actively
programming or erasing causes subsequent reads from the device to output invalid
data. Valid array data is output only after the program or erase operation has finished.
Upon completion of array programming, the Status Register indicates ready (SR.7 = 1).
A full Status Register check should be performed to check for any programming errors,
then cleared by using the Clear Status Register command.
Additional buffered programming operations can be initiated by issuing another setup
command, and repeating the buffered programming bus-cycle sequence. However, any
errors in the Status Register must first be cleared before another buffered
programming operation can be initiated.
9.4
Block Erase Operations
Erasing a block changes ‘zeros’ to ‘ones’. To change ones to zeros, a program operation
must be performed (See Section 9.3, “Programming Operations”). Erasing is performed
on a block basis - an entire block is erased each time an erase command sequence is
issued. Once a block is fully erased, all addressable locations within that block read as
logical ones (FFFFh for x16 mode, FFh for x8 mode). Only one block-erase operation
can occur at a time, and is not permitted during a program suspend.
To perform a block-erase operation, issue the Block Erase command sequence at the
desired block address. Table 23 shows the two-cycle Block Erase command sequence.

Block Erase
Block Address
Note:
A block-erase operation requires the addressed block to be unlocked, and a valid
voltage applied to VPEN throughout the block-erase operation. Otherwise, the
operation will abort, setting the appropriate Status Register error bit(s).
The Erase Confirm command latches the address of the block to be erased. The
addressed block is preconditioned (programmed to all zeros), erased, and then verified.
The read mode of the device is automatically changed to Read Status Register mode,
and remains in effect until another read-mode command is issued.
During a block-erase operation, STS and the Status Register indicates a busy status
(SR.7 = 0). Upon completion, STS and the Status Register indicates a ready status
(SR.7 = 1). The Status Register should be checked for any errors, then cleared. If any
errors did occur, subsequent erase commands to the device are ignored unless the
Status Register is cleared.
The only valid commands during a block erase operation are Read Array, Read Device
Information, CFI Query, and Erase Suspend. After the block-erase operation has
completed, any valid command can be issued.

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)
Note:
Issuing the Read Array command to the device while it is actively erasing causes
subsequent reads from the device to output invalid data. Valid array data is output only
after the block-erase operation has finished.
Standby power levels are not be realized until the block-erase operation has finished.
Also, asserting RP# aborts the block-erase operation, and array contents at the
addressed location are indeterminate. The addressed block should be erased before
programming within the block is attempted.
9.5
Blank Check
The Blank Check operation determines whether a specified array block is blank (i.e.
completely erased). Without Blank Check, Block Erase would be the only other way to
ensure a block is completely erased. Blank Check is especially useful in the case of
erase operation interrupted by a power loss event.
Blank Check can apply to only one block at a time, and no operations other than Status
Register Reads are allowed during Blank Check (e.g. reading array data, program,
erase etc.). Suspend and resume operations are not supported during Blank Check, nor
is Blank Check supported during any suspended operations.
Blank Check operations are initiated by writing the Block Blank Check command to the
block address. Next, the Blank Check Confirm command is issued along with the same
block address. When a successful command sequence is entered, the device
automatically enters the Read Status State. The WSM then reads the entire specified
block, and determines whether any bit in the block is programmed or over-erased.
The status register can be examined for Blank Check progress and errors by reading
any address within the block being accessed. During a blank check operation, the
Status Register indicates a busy status (SR.7 = 0). Upon completion, the Status
Register indicates a ready status (SR.7 = 1). The Status Register should be checked for
any errors, and then cleared. If the Blank Check operation fails, which means the block
is not completely erased, the Status Register bit SR.5 will be set (“1”). CE# or OE#
toggle (during polling) updates the Status Register.
The device remains in Status Register Mode until another command is written to the
device. After examining the Status Register, it should be cleared by the Clear Status
Register command before issuing a new command. Any command can follow once the
Blank Check command is complete.
9.6
Suspend and Resume
An erase or programming operation can be suspended to perform other operations, and
then subsequently resumed. Table 24 shows the Suspend and Resume command bus-
cycles.
Note:
All erase and programming operations require the addressed block to remain unlocked
with a valid voltage applied to VPEN throughout the suspend operation. Otherwise, the
block-erase or programming operation will abort, setting the appropriate Status
Register error bit(s). Also, asserting RP# aborts suspended block-erase and

To suspend an on-going erase or program operation, issue the Suspend command to
any device address. The program or erase operation suspends at pre-determined points
during the operation after a delay of tSUSP. Suspend is achieved whenSTS (in RY/BY#
mode) goes high, SR[7,6] = 1 (erase-suspend) or SR[7,2] = 1 (program-suspend).
Note:
Issuing the Suspend command does not change the read mode of the device. The
device will be in Read Status Register mode from when the erase or program command
was first issued, unless the read mode was changed prior to issuing the Suspend
command.
Not all commands are allowed when the device is suspended. Table 25 shows which
device commands are allowed during Program Suspend or Erase Suspend.

To resume a suspended program or erase operation, issue the Resume command to
any device address. The read mode of the device is automatically changed to Read
Status Register. The operation continues where it left off, STS (in RY/BY# mode) goes
low, and the respective Status Register bits are cleared.
When the Resume command is issued during a simultaneous erase-suspend/ program-
suspend condition, the programming operation is resumed first. Upon completion of the
programming operation, the Status Register should be checked for any errors, and
cleared. The resume command must be issued again to complete the erase operation.
Upon completion of the erase operation, the Status Register should be checked for any
errors, and cleared.
9.7
Status Signal
The STATUS (STS) signal can be configured to different states using the STS
Configuration command (Table 26). Once the STS signal has been configured, it
remains in that configuration until another Configuration command is issued or RP# is
asserted low. Initially, the STS signal defaults to RY/BY# operation where RY/BY# low
indicates that the WSM is busy. RY/BY# high indicates that the state machine is ready
for a new operation or suspended. Table 27 displays possible STS configurations.

To reconfigure the STATUS (STS) signal to other modes, the Configuration command is
given followed by the desired configuration code. The three alternate configurations are
all pulse mode for use as a system interrupt as described in the following paragraphs.
For these configurations, bit 0 controls Erase Complete interrupt pulse, and bit 1
controls Program Complete interrupt pulse. Supplying the 00h configuration code with
the Configuration command resets the STS signal to the default RY/BY# level mode.
The Configuration command may only be given when the device is not busy or
suspended. Check SR.7 for device status. An invalid configuration code will result in
SR.4 and SR.5 being set.
Note:
STS Pulse mode is not supported in the Clear Lock Bits and Set Lock Bit commands.

Security and Protection
J3 65 nm SBC device offers both hardware and software security features. Block lock
operations, PRs and VPEN allow users to implement various levels of data protection.
9.8.1
Normal Block Locking
J3 65 nm SBC has the capability of Flexible Block Locking (locked blocks remain locked
upon reset or power cycle): All blocks within the device are in unlocked state when ship
from Numonyx. Blocks can be locked individually by issuing the Set Block Lock Bit
command sequence to any address within a block. Once locked, blocks remain locked
when power is removed, or when the device is reset.
All locked blocks are unlocked simultaneously by issuing the Clear Block Lock Bits
command sequence to any device address. Locked blocks cannot be erased or
programmed. Table 28 summarizes the command bus-cycles.

After issuing the Set Block Lock Bit setup command or Clear Block Lock Bits setup
command, the device’s read mode is automatically changed to Read Status Register
mode. After issuing the confirm command, completion of the operation is indicated by
STS (in RY/BY# mode) going high and SR.7 = 1.
Blocks cannot be locked or unlocked while programming or erasing, or while the device
is suspended. Reliable block lock and unlock operations occur only when VCC and VPEN
are valid. When VPEN ≤ VPENLK, block lock-bits cannot be changed.

When the set lock-bit operation is complete, SR.4 should be checked for any error.
When the clear lock-bit operation is complete, SR.5 should be checked for any error.
Errors bits must be cleared using the Clear Status Register command.
Block lock-bit status can be determined by first issuing the Read Device Information
command, and then reading from <block base address> + 02h. DQ0 indicates the lock
status of the addressed block (0 = unlocked, 1 = locked).
9.8.2
9.8.3
Configurable Block Locking
J3 65 nm SBC devices feature user-configurable block locking. This feature can be
implemented to protect and/or secure the user’s system. The user can individually set
each block as Non-Volatile Temporary, Non-Volatile Semi-Permanent or Non-Volatile
Permanent. For additional information and collateral, please contact the sales
representative.
Password Access
Password Access is a security enhancement offered on the J3 65 nm SBC device. This
feature protects information stored in main-array memory blocks by preventing content
alteration or reads, until a valid 64-bit password is received. Password Access may be
combined with Non-Volatile Protection and/or Volatile Protection to create a multi-
tiered solution.
Please contact your Numonyx Sales for further details concerning Password Access.
9.8.4
128-bit OTP Protection Register
J3 65 nm SBC includes a 128-bit Protection Register (PR) that can be used to increase
the security of a system design. For example, the number contained in the PR can be
used to “match” the flash component with other system components such as the CPU
or ASIC, hence preventing device substitution.
The 128-bits of the PR are divided into two 64-bit segments:
• One segment is programmed at the Numonyx factory with a unique unalterable 64-
bit number.
• The other segment is left blank for customer designers to program as desired. Once
the customer segment is programmed, it can be locked to prevent further
programming.
9.8.5
9.8.6
Reading the 128-bit OTP Protection Register
The Protection Register is read in Identification Read mode. The device is switched to
this mode by issuing the Read Identifier command (0090h). Once in this mode, read
cycles from addresses shown in Table 31, “Word-Wide Protection Register Addressing”
or Table 32, “Byte-Wide Protection Register Addressing” retrieve the specified
information. To return to Read Array mode, write the Read Array command (00FFh).
Programming the 128-bit OTP Protection Register
PR bits are programmed using the two-cycle Program OTP Register command. The 64-
bit number is programmed 16 bits at a time for word-wide configuration and eight bits
at a time for byte-wide configuration. First write the Protection Program Setup
command, 00C0h. The next write to the device will latch in address and data and
program the specified location. The allowable addresses are shown in Table 31, “Word-
Wide Protection Register Addressing” on page 45 or Table 32, “Byte-Wide Protection
Register Addressing” on page 45. See Figure 24, “Protection Register Programming

outside the defined PR address space will result in a Status Register error (SR.4 will be
set). Attempting to program a locked PR segment will result in a Status Register error
(SR.4 and SR.1 will be set).

Locking the 128-bit OTP Protection Register
The user-programmable segment of the PR is lockable by programming Bit 1 of the
Protection Lock Register (PLR) to 0. Bit 0 of this location is programmed to 0 at the
Numonyx factory to protect the unique device number. Bit 1 is set using the Protection
Program command to program “0xFFFD” to the PLR. After these bits have been
programmed, no further changes can be made to the values stored in the Protection
Register. Protection Program commands to a locked section will result in a Status
Register error (SR.4 and SR.1 will be set). The PR lockout state is not reversible.

VPEN Protection
When it’s necessary to protect the entire array, global protection can be achieved using
a hardware mechanism using VPEN. Whenever a valid voltage is present on VPEN,
blocks within the main flash array can be erased or programmed. By grounding VPEN,
blocks within the main array cannot be altered – attempts to program or erase blocks
will fail resulting in the setting of the appropriate error bit in the Status Register. By
holding VPEN low, absolute write protection of all blocks in the array can be achieved.

Device Command Codes
For a complete definition on device operations refer to Section 8.4, “Device Commands”
on page 33. The list of all applicable commands are included here one more time for
the convenience.
Note:
Some customer applications use illegal or invalid commands (like 0x00) accidentally or
intentionally with the device. An illegal or invalid command caused the device output to
change to Array Read mode on 130nm. On the 65nm device, the output will change to
Read Status Register mode.
After an illegal or invalid command, software may attempt to read the device. If the
illegal command was intentional, software will expect to read array data on 130nm
device, such as 0xFFFF in an unprogrammed location. On the 65nm device, software
may not get the expected array data and instead the status register is read.
Please refer to the legal and valid commands/spec defined in the Datasheet, such as
forread mode, issue 0xFF to Read Array mode, 0x90 to Read Signature, 0x98 to Read
CFI/OTP array mode.

Common Flash Interface
The CFI specification outlines device and host system software interrogation handshake
which allows specific vendor-specified software algorithms to be used for entire families
of devices. This allows device independent, JEDEC ID-independent, and forward- and
backward-compatible software support for the specified flash device families. It allows
flash vendors to standardize their existing interfaces for long-term compatibility.
This section defines the data structure or “database” returned by the (CFI) Query
command. System software should parse this structure to gain critical information such
as block size, density, x8/x16, and electrical specifications. Once this information has
been obtained, the software will know which command sets to use to enable flash
writes, block erases, and otherwise control the flash component. The Query is part of
an overall specification for multiple command set and control interface descriptions
called CFI.
13.1
Query Structure Output
The Query “database” allows system software to gain information for controlling the
flash component. This section describes the device’s CFI-compliant interface that allows
the host system to access Query data.
Query data are always presented on the lowest-order data outputs (D[7:0]) only. The
numerical offset value is the address relative to the maximum bus width supported by
the device. On this family of devices, the Query table device starting address is a 10h,
which is a word address for x16 devices.
For a word-wide (x16) device, the first two bytes of the Query structure, “Q” and “R” in
ASCII, appear on the low byte at word addresses 10h and 11h. This CFI-compliant
device outputs 00h data on upper bytes. Thus, the device outputs ASCII “Q” in the low
byte (D[7:0]) and 00h in the high byte (D[15:8]).
At Query addresses containing two or more bytes of information, the least significant
data byte is presented at the lower address, and the most significant data byte is
presented at the higher address.
In all of the following tables, addresses and data are represented in hexadecimal
notation, so the “h” suffix has been dropped. In addition, since the upper byte of word-
wide devices is always “00h,” the leading “00” has been dropped from the table
notation and only the lower byte value is shown. Any x16 device outputs can be
assumed to have 00h on the upper byte in this mode.
