Micron’s 8Mb SyncBurst SRAMs integrate a 512K x
18, 256K x 32, or 256K x 36 SRAM core with advanced
synchronous peripheral circuitry and a 2-bit burst
counter. All synchronous inputs pass through registers
controlled by a positive-edge-triggered single-clock in-
put (CLK). The synchronous inputs include all ad-
dresses, all data inputs, active LOW chip enable (CE#),
two additional chip enables for easy depth expansion
(CE2, CE2#), burst control inputs (ADSC#, ADSP#,
ADV#), byte write enables (BWx#) and global write
None

GENERAL DESCRIPTION (continued)
(GW#). Note that CE2# is not available on the
T Version.
DQc pins and DQPc; BWd# controls DQd pins and
DQPd. GW# LOW causes all bytes to be written. Parity
bits are only available on the x18 and x36 versions.
This device incorporates a single-cycle deselect fea-
ture during READ cycles. If the device is immediately
deselected after a READ cycle, the output bus goes to a
High-Z state tKQHZ nanoseconds after the rising edge
of clock.
Micron’s 8Mb SyncBurst SRAMs operate from a
+3.3V VDD power supply, and all inputs and outputs are
TTL-compatible. Users can choose either a 3.3V or 2.5V
I/O version. The device is ideally suited for Pentium
and PowerPC pipelined systems and systems that ben-
efit from a very wide, high-speed data bus. The device
is also ideal in generic 16-, 18-, 32-, 36-, 64-, and 72-bit-
wide applications.
Asynchronous inputs include the output enable
(OE#), clock (CLK) and snooze enable (ZZ). There is also
a burst mode input (MODE) that selects between inter-
leaved and linear burst modes. The data-out (Q), en-
abled by OE#, is also asynchronous. WRITE cycles can
be from one to two bytes wide (x18) or from one to four
bytes wide (x32/x36), as controlled by the write control
inputs.
Burst operation can be initiated with either address
status processor (ADSP#) or address status controller
(ADSC#) inputs. Subsequent burst addresses can be
internally generated as controlled by the burst advance
input (ADV#).
Address and write control are registered on-chip to
simplify WRITE cycles. This allows self-timed WRITE
cycles. Individual byte enables allow individual bytes
to be written. During WRITE cycles on the x18 device,
BWa# controls DQa pins and DQPa; BWb# controls
DQb pins and DQPb. During WRITE cycles on the x32
and x36 devices, BWa# controls DQa pins and DQPa;
BWb# controls DQb pins and DQPb; BWc# controls

TQFP PINOUTS
At the time of the writing of this data sheet, there are
two pinouts in the industry. Micron will support both
pinouts for this part.

Input Synchronous Address Status Controller: This active LOW input
interrupts any ongoing burst, causing a new external address to be
registered. A READ or WRITE is performed using the new address if
CE# is LOW. ADSC# is also used to place the chip into power-down
state when CE# is HIGH.

for a WRITE cycle and HIGH for a READ cycle. For the x18 version,
BWa# controls DQa’s and DQPa; BWb# controls DQb’s and DQPb.
For the x32 and x36 versions, BWa# controls DQa’s and DQPa; BWb#
controls DQb’s and DQPb; BWc# controls DQc’s and DQPc; BWd#
controls DQd’s and DQPd. Parity is only available on the x18 and x36

Input Synchronous Address Advance: This active LOW input is used to
advance the internal burst counter, controlling burst access after
the external address is loaded. A HIGH on ADV# effectively causes
wait states to be generated (no address advance). To ensure use of
correct address during a WRITE cycle, ADV# must be HIGH at the
rising edge of the first clock after an ADSP# cycle is initiated.

NOTE: 1. X means “Don’t Care.” # means active LOW. H means logic HIGH. L means logic LOW.
2. For WRITE#, L means any one or more byte write enable signals (BWa#, BWb#, BWc# or BWd#) and BWE# are LOW or
GW# is LOW. WRITE# = H for all BWx#, BWE#, GW# HIGH.
3. BWa# enables WRITEs to DQa’s and DQPa. BWb# enables WRITEs to DQb’s and DQPb. BWc# enables WRITEs to DQc’s
and DQPc. BWd# enables WRITEs to DQd’s and DQPd. DQPa and DQPb are only available on the x18 and x36 versions.
DQPc and DQPd are only available on the x36 version.
4. All inputs except OE# and ZZ must meet setup and hold times around the rising edge (LOW to HIGH) of CLK.
5. Wait states are inserted by suspending burst.
6. For a WRITE operation following a READ operation, OE# must be HIGH before the input data setup time and held
HIGH throughout the input data hold time.
7. This device contains circuitry that will ensure the outputs will be in High-Z during power-up.
8. ADSP# LOW always initiates an internal READ at the L-H edge of CLK. A WRITE is performed by setting one or more
byte write enable signals and BWE# LOW or GW# LOW for the subsequent L-H edge of CLK. Refer to WRITE timing
diagram for clarification.

NOTE: 1. Test conditions as specified with the output loading shown in Figure 1 for 3.3V I/O (VDDQ = +3.3V +0.3V/-0.165V) and
Figure 3 for 2.5V I/O (VDDQ = +2.5V +0.4V/-0.125V) unless otherwise noted.
2. Measured as HIGH above VIH and LOW below VIL.
3. This parameter is measured with output load as shown in Figure 2 for 3.3V I/O and Figure 4 for 2.5V I/O.
4. This parameter is sampled.
5. Transition is measured 500mV from steady state voltage.
6. Refer to Technical Note TN-58-09, “Synchronous SRAM Bus Contention Design Considerations,” for a more thorough
discussion on these parameters.
7. OE# is a “Don’t Care” when a byte write enable is sampled LOW.
8. A WRITE cycle is defined by at least one byte write enable LOW and ADSP# HIGH for the required setup and hold
times. A READ cycle is defined by all byte write enables HIGH and ADSC# or ADV# LOW or ADSP# LOW for the required
setup and hold times.
9. This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of CLK
when either ADSP# or ADSC# is LOW and chip enabled. All other synchronous inputs must meet the setup and hold
times with stable logic levels for all rising edges of clock (CLK) when the chip is enabled. Chip enable must be valid at
each rising edge of CLK when either ADSP# or ADSC# is LOW to remain enabled.

SNOOZE MODE
SNOOZE MODE is a low-current, “power-down”
mode in which the device is deselected and current is
reduced to ISB2Z. The duration of SNOOZE MODE is
dictated by the length of time ZZ is in a HIGH state.
After the device enters SNOOZE MODE, all inputs
except ZZ become gated inputs and are ignored.
ZZ is an asynchronous, active HIGH input that
causes the device to enter SNOOZE MODE. When ZZ
becomes a logic HIGH, ISB2Z is guaranteed after the
setup time tZZ is met. Any READ or WRITE operation
pending when the device enters SNOOZE MODE is not
guaranteed to complete successfully. Therefore,
SNOOZE MODE must not be initiated until valid pend-
ing operations are completed.

NOTE: 1. Q(A2) refers to output from address A2. Q(A2 + 1) refers to output from the next internal burst address following A2.
2. CE2# and CE2 have timing identical to CE#. On this diagram, when CE# is LOW, CE2# is LOW and CE2 is HIGH. When
CE# is HIGH, CE2# is HIGH and CE2 is LOW.
3. Timing is shown assuming that the device was not enabled before entering into this sequence. OE# does not cause Q
to be driven until after the following clock rising edge.
4. Outputs are disabled within one clock cycle after deselect.

NOTE: 1. D(A2) refers to input for address A2. D(A2 + 1) refers to input for the next internal burst address following A2.
2. CE2# and CE2 have timing identical to CE#. On this diagram, when CE# is LOW, CE2# is LOW and CE2 is HIGH.
When CE# is HIGH, CE2# is HIGH and CE2 is LOW.
3. OE# must be HIGH before the input data setup and held HIGH throughout the data hold time. This prevents
input/output data contention for the time period prior to the byte write enable inputs being sampled.
4. ADV# must be HIGH to permit a WRITE to the loaded address.
5. Full-width WRITE can be initiated by GW# LOW; or GW# HIGH and BWE#, BWa# and BWb# LOW for x18 device;
or GW# HIGH and BWE#, BWa#-BWd# LOW for x32 and x36 devices.
