PRODUCT DESCRIPTION
The SST32HF324C ComboMemory devices integrate a
CMOS flash memory bank with a CMOS SRAM mem-
ory bank in a Multi-Chip Package (MCP), manufactured
with SST’s proprietary, high-performance SuperFlash
technology.
The SST32HF324C provide the added functionality of
being able to simultaneously read from or write to the
SRAM bank while erasing or programming in the flash
memory bank. The SRAM memory bank can be read or
written while the flash memory bank performs Sector-
Erase, Bank-Erase, or Word-Program concurrently. All
flash memory Erase and Program operations will automati-
cally latch the input address and data signals and complete
the operation in background without further input stimulus
requirement. Once the internally controlled Erase or Pro-
gram cycle in the flash bank has commenced, the SRAM
bank can be accessed for Read or Write.
Featuring high performance Word-Program, the flash
memory bank provides a maximum Word-Program time of
7 µsec. To protect against inadvertent flash write, the
SST32HF324C devices contain on-chip hardware and
software data protection schemes. The SST32HF324C
devices offer a guaranteed endurance of 10,000 cycles.
Data retention is rated at greater than 100 years.
The SST32HF324C devices are suited for applications that
use both flash memory and SRAM memory to store code
or data. For systems requiring low power and small form
factor, the SST32HF324C devices significantly improve
performance and reliability while lowering power consump-
tion when compared with multiple chip solutions. The
SST32HF324C inherently use less energy during Erase
and Program operations than alternative flash technolo-
gies. The total energy consumed is a function of the
applied voltage, current, and time of application. Since, for
any given voltage range, SuperFlash technology uses less
current to program and has a shorter erase time, the total
energy consumed during any Erase or Program operation
is less than alternative flash technologies.
The SST32HF324C devices consist of two independent
memory banks with respective bank enable signals. The
Flash and SRAM memory banks are superimposed in the
same memory address space. Both memory banks share
common address lines, data lines, WE# and OE#. The
memory bank selection is done by memory bank enable
signals. The SRAM bank enable signal, BES# selects the
SRAM bank. The flash memory bank enable signal, BEF#
selects the flash memory bank. The WE# signal has to be
used with Software Data Protection (SDP) command
sequence when controlling the Erase and Program opera-
tions in the flash memory bank. The SDP command
sequence protects the data stored in the flash memory
bank from accidental alteration.

SST32HF324C
Preliminary Specifications
SuperFlash technology provides fixed Erase and Program
times independent of the number of Erase/Program cycles
that have occurred. Therefore the system software or hard-
ware does not have to be modified or de-rated as is neces-
sary with alternative flash technologies, whose Erase and
Program times increase with accumulated Erase/Program
cycles.
Flash Word-Program Operation
The flash memory bank of the SST32HF324C devices is
programmed on a word-by-word basis. Before Program
operations, the memory must be erased first. The Program
operation consists of three steps. The first step is the three-
byte load sequence for Software Data Protection. The sec-
ond step is to load word address and word data. During the
Word-Program operation, the addresses are latched on the
falling edge of either BEF# or WE#, whichever occurs last.
The data is latched on the rising edge of either BEF# or
WE#, whichever occurs last. The third step is the internal
Program operation which is initiated after the rising edge of
the fourth WE# or BEF#, whichever occurs first. The Pro-
gram operation, once initiated, will be completed, within 10
µs. See Figures 6 and 7 for WE# and BEF# controlled Pro-
gram operation timing diagrams and Figure 18 for flow-
charts. During the Program operation, the only valid flash
Read operations are Data# Polling and Toggle Bit. During
the internal Program operation, the host is free to perform
additional tasks. Any SDP commands loaded during the
internal Program operation will be ignored.
Device Operation
The ComboMemory uses BES# and BEF# to control oper-
ation of either the SRAM or the flash memory bank. When
BES# is low, the SRAM Bank is activated for Read and
Write operation. When BEF# is low the flash bank is acti-
vated for Read, Program or Erase operation. BES# and
BEF# cannot be at low level at the same time. If BES# and
BEF# are both asserted to low level bus contention will
result and the device may suffer permanent damage.
All address, data, and control lines are shared by SRAM
Bank and flash bank which minimizes power consumption
and loading. The device goes into standby when both bank
enables are high.
Flash Sector-/Block-Erase Operation
Concurrent Read/Write Operation
The Flash Sector/Block-Erase operation allows the system
to erase the device on a sector-by-sector (or block-by-
block) basis. The SST32HF324C offer both Sector-Erase
and Block-Erase mode. The sector architecture is based
on uniform sector size of 2 KWord. The Block-Erase mode
is based on uniform block size of 32 KWord. The Sector-
Erase operation is initiated by executing a six-byte com-
mand sequence with Sector-Erase command (30H) and
sector address (SA) in the last bus cycle. The address lines
The SST32HF324C provide the unique benefit of being
able to read from or write to SRAM, while simultaneously
erasing or programming the flash. This allows data alter-
ation code to be executed from SRAM, while altering the
data in flash. See Figure 22 for a flowchart. The following
table lists all valid states.
CONCURRENT READ/WRITE STATE TABLE
Flash
Program/Erase
Program/Erase
SRAM
Read
Write
AMS-A11 are used to determine the sector address. The
Block-Erase operation is initiated by executing a six-byte
command sequence with Block-Erase command (50H)
and block address (BA) in the last bus cycle. The address
lines AMS-A15 are used to determine the block address.
The sector or block address is latched on the falling edge of
the sixth WE# pulse, while the command (30H or 50H) is
latched on the rising edge of the sixth WE# pulse. The
internal Erase operation begins after the sixth WE# pulse.
The End-of-Erase operation can be determined using
either Data# Polling or Toggle Bit methods. See Figures 11
and 12 for timing waveforms. Any commands issued during
the Sector- or Block-Erase operation are ignored.
The device will ignore all SDP commands when an Erase
or Program operation is in progress. Note that Product
Identification commands use SDP; therefore, these com-
mands will also be ignored while an Erase or Program
operation is in progress.
Flash Read Operation
The Read operation of the SST32HF324C devices is con-
trolled by BEF# and OE#. Both have to be low, with WE#
high, for the system to obtain data from the outputs. BEF#
is used for flash memory bank selection. When BEF# is
high, the chip is deselected and only standby power is
consumed. OE# is the output control and is used to gate
data from the output pins. The data bus is in high imped-
ance state when OE# is high. Refer to Figure 5 for further
details.

Preliminary Specifications
Erase-Suspend/-Resume Commands
Write Operation Status Detection
The Erase-Suspend operation temporarily suspends a
Sector- or Block-Erase operation thus allowing data to be
read from any memory location, or program data into any
sector/block that is not suspended for an Erase operation.
The operation is executed by issuing one byte command
sequence with Erase-Suspend command (B0H). The
device automatically enters read mode typically within 20
µs after the Erase-Suspend command had been issued.
Valid data can be read from any sector or block that is not
suspended from an Erase operation. Reading at address
location within erase-suspended sectors/blocks will output
DQ2 toggling and DQ6 at “1”. While in Erase-Suspend
mode, a Word-Program operation is allowed except for the
sector or block selected for Erase-Suspend.
The SST32HF324C provide two software means to detect
the completion of a write (Program or Erase) cycle, in order
to optimize the system Write cycle time. The software
detection includes two status bits: Data# Polling (DQ7) and
Toggle Bit (DQ6). The End-of-Write detection mode is
enabled after the rising edge of WE#, which initiates the
internal Program or Erase operation.
The actual completion of the nonvolatile write is asynchro-
nous with the system; therefore, either a Data# Polling or
Toggle Bit read may be simultaneous with the completion
of the Write cycle. If this occurs, the system may possibly
get an erroneous result, i.e., valid data may appear to con-
flict with either DQ7 or DQ6. In order to prevent spurious
rejection, if an erroneous result occurs, the software routine
should include a loop to read the accessed location an
additional two (2) times. If both reads are valid, then the
device has completed the Write cycle, otherwise the rejec-
tion is valid.
To resume Sector-Erase or Block-Erase operation which
has been suspended the system must issue Erase
Resume command. The operation is executed by issuing
one byte command sequence with Erase Resume com-
mand (30H) at any address in the last Byte sequence.
Flash Data# Polling (DQ7)
Flash Chip-Erase Operation
When the SST32HF324C flash memory banks are in the
internal Program operation, any attempt to read DQ7 will
produce the complement of the true data. Once the Pro-
gram operation is completed, DQ7 will produce true data.
Note that even though DQ7 may have valid data immedi-
ately following the completion of an internal Write opera-
tion, the remaining data outputs may still be invalid: valid
data on the entire data bus will appear in subsequent suc-
cessive Read cycles after an interval of 1 µs. During inter-
nal Erase operation, any attempt to read DQ7 will produce
a ‘0’. Once the internal Erase operation is completed, DQ7
will produce a ‘1’. The Data# Polling is valid after the rising
edge of the fourth WE# (or BEF#) pulse for Program opera-
tion. For Sector- or Block-Erase, the Data# Polling is valid
after the rising edge of the sixth WE# (or BEF#) pulse. See
Figure 8 for Data# Polling timing diagram and Figure 19 for
a flowchart.
The SST32HF324C provide a Chip-Erase operation, which
allows the user to erase the entire memory array to the “1”
state. This is useful when the entire device must be quickly
erased.
The Chip-Erase operation is initiated by executing a six-
byte command sequence with Chip-Erase command (10H)
at address 5555H in the last byte sequence. The Erase
operation begins with the rising edge of the sixth WE# or
BEF#, whichever occurs first. During the Erase operation,
the only valid read is Toggle Bit or Data# Polling. See Table
5 for the command sequence, Figure 9 for timing diagram,
and Figure 21 for the flowchart. Any commands issued dur-
ing the Chip-Erase operation are ignored.

SST32HF324C
Preliminary Specifications
Toggle Bits (DQ6 and DQ2)
Flash Software Data Protection (SDP)
During the internal Program or Erase operation, any con-
secutive attempts to read DQ6 will produce alternating “1”s
and “0”s, i.e., toggling between 1 and 0. When the internal
Program or Erase operation is completed, the DQ6 bit will
stop toggling. The device is then ready for the next opera-
tion. For Sector-, Block-, or Chip-Erase, the toggle bit (DQ6)
is valid after the rising edge of sixth WE# (or BEF#) pulse.
DQ6 will be set to “1” if a Read operation is attempted on an
Erase-Suspended Sector/Block. If Program operation is ini-
tiated in a sector/block not selected in Erase-Suspend
mode, DQ6 will toggle.
The SST32HF324C provide the JEDEC approved soft-
ware data protection scheme for all flash memory bank
data alteration operations, i.e., Program and Erase. Any
Program operation requires the inclusion of a series of
three-byte sequence. The three byte-load sequence is
used to initiate the Program operation, providing optimal
protection from inadvertent Write operations, e.g., during
the system power-up or power-down. Any Erase operation
requires the inclusion of six-byte load sequence. The
SST32HF324C devices are shipped with the software data
protection permanently enabled. See Table 5 for the spe-
cific software command codes. During SDP command
sequence, invalid commands will abort the device to Read
mode, within TRC. The contents of DQ15-DQ8 can be VIL or
VIH, but no other value, during any SDP command
sequence.
An additional Toggle Bit is available on DQ2, which can be
used in conjunction with DQ6 to check whether a particular
sector is being actively erased or erase-suspended. Table 1
shows detailed status bits information. The Toggle Bit
(DQ2) is valid after the rising edge of the last WE# (or
BEF#) pulse of Write operation. See Figure 9 for Toggle Bit
timing diagram and Figure 19 for a flowchart.
SRAM Read
The SRAM Read operation of the SST32HF324C is con-
trolled by OE# and BES#, both have to be low with WE#
high for the system to obtain data from the outputs. BES# is
used for SRAM bank selection. OE# is the output control
and is used to gate data from the output pins. The data bus
is in high impedance state when OE# is high. Refer to the
Read cycle timing diagram, Figure 2, for further details.

rising edge of either BES# or WE#, whichever occurs first.
The Write time is measured from the last falling edge of
BES# or WE# to the first rising edge of BES# or WE#.

Flash Memory Data Protection
The SST32HF324C flash memory bank provides both
hardware and software features to protect nonvolatile data
from inadvertent writes.
Product Identification
The Product Identification mode identifies the devices as
the SST32HF324C and manufacturer as SST. This mode
may be accessed by software operations only. The
hardware device ID Read operation, which is typically
used by programmers, cannot be used on this device
because of the shared lines between flash and SRAM
in the multi-chip package. Therefore, application of
high voltage to pin A9 may damage this device. Users
may use the software Product Identification operation to
identify the part (i.e., using the device ID) when using multi-
ple manufacturers in the same socket. For details, see
Flash Hardware Data Protection
Noise/Glitch Protection: A WE# or BEF# pulse of less than
5 ns will not initiate a Write cycle.
VDD Power Up/Down Detection: The Write operation is
inhibited when VDD is less than 1.5V.
Write Inhibit Mode: Forcing OE# low, BEF# high, or WE#
high will inhibit the flash Write operation. This prevents
inadvertent writes during power-up or power-down.

Security ID
The SST32HF324C device offers one 128-bit Security ID
space. This space is left un-programmed for the customer
to program as desired.
TABLE 2: PRODUCT IDENTIFICATION
To program the Security ID, the user must use the Security
ID Word-Program command. To detect end-of-write for the
SEC ID, read the toggle bits. Do not use Data# Polling.
Once this is complete, the Sec ID should be locked using
the User Sec ID Program Lock-Out. This disables any
future corruption of this space. Note that regardless of
whether or not the Sec ID is locked, the Sec ID segment
cannot be erased.

Product Identification Mode Exit/Reset
In order to return to the standard read mode, the Software
Product Identification mode must be exited. Exiting is
accomplished by issuing the Exit ID command sequence,
which returns the device to the Read operation. Please
note that the software reset command is ignored during an
internal Program or Erase operation. This command may
also be used to reset the device to Read mode after any
inadvertent transient condition that apparently causes the
device to behave abnormally, e.g. not read correctly. See
Table 5 for software command codes, Figure 14 for timing
waveform and Figure 20 for a flowchart.
The Secure ID space can be queried by executing a three-
byte command sequence with Enter Sec ID command
(88H) at address 5555H in the last byte sequence. To exit
this mode, the Exit Sec ID command should be executed.
Refer to Table 5 for more details.
Design Considerations
SST recommends a high frequency 0.1 µF ceramic capac-
itor to be placed as close as possible between VDD and
VSS, e.g., less than 1 cm away from the VDD pin of the
device. Additionally, a low frequency 4.7 µF electrolytic
capacitor from VDD to VSS should be placed within 1 cm of
the VDD pin.
