Micron’s 18Mb SyncBurst SRAMs integrate a 1 Meg x
18, ±12K x 32, or ±12K 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
input (CLK). The synchronous inputs include all
addresses, 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 (GW#).
DQPb; BWc# controls DQc pins/balls and DQPc; BWd#
controls DQd pins/balls and DQPd. GW# LOW causes
all bytes to be written. Parity bits are only available on
the x18 and x36 versions.
Asynchronous inputs include the output enable
(OE#), clock (CLK) and snooze enable (ZZ). There is
also a burst mode input (MODE) that selects between
interleaved and linear burst modes. The data out (Q) is
enabled by OE#. 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.
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
t
High-Z state KQHZ nanoseconds after the rising edge
of clock.
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#).
The device is ideally suited for Pentium and Pow-
erPC pipelined systems and systems that benefit 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.
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/balls and DQPa; BWb# con-
trols DQb pins/balls and DQPb. During WRITE cycles
on the x32 and x36 devices, BWa# controls DQa pins/
balls and DQPa; BWb# controls DQb pins/balls and

DESCRIPTION
ADSC#
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.
ADSP#
ADV#
Input Synchronous Address Status Processor: This active LOW input interrupts any ongoing burst,
causing a new external address to be registered. A READ is performed using the new address,
independent of the byte write enables and ADSC#, but dependent upon CE#, CE2, and CE2#.
ADSP# is ignored if CE# is HIGH. Power-down state is entered if CE2 is LOW or CE2# is HIGH.
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 this pin
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.
BWa#
BWb#
BWc#
BWd#
Input
Synchronous Byte Write: These active LOW inputs allow individual bytes to be written when a
WRITE cycle is active and must meet the setup and hold times around the rising edge of CLK.
BWs need to be asserted on the same cycle as the address. To enable the BW’s functionality, the
byte write enable (BWE#) input must be asserted LOW. BWa# controls DQa pins; BWb# controls
DQb pins; BWc# controls DQc pins; and BWd# controls DQa pins.
BWE#
CE#
Input
Byte Write Enable: This active LOW input permits BYTE WRITE operations and must meet the
setup and hold times around the rising edge of CLK.
Input Synchronous Chip Enable: This active LOW input is used to enable the device and conditions the
internal use of ADSP#. CE# is sampled only when a new external address is loaded.
CE2#
CE2
Input
Synchronous Chip Enable: This active LOW input is used to enable the device and is sampled only
when a new external address is loaded.
Input
Synchronous Chip Enable: This active HIGH input is used to enable the device and is sampled only
when a new external address is loaded.
CLK
Input Clock: This signal registers the address, data, chip enable, byte write enables, and burst control
inputs on its rising edge. All synchronous inputs must meet setup and hold times around the
clock’s rising edge.
GW#
Input
Global Write: This active LOW input allows a full 18-, 32-, or 36-bit WRITE to occur independent
of the BWE# and BWx# lines and must meet the setup and hold times around the rising edge of
CLK.
MODE (LBO#)
OE# (G#)
Input
Mode: This input selects the burst sequence. A LOW on this pin selects “linear burst.” NC or HIGH
on this pin selects “interleaved burst.” Do not alter input state while device is operating. LBO# is
the JEDEC-standard term for MODE.
Input Output Enable: This active LOW, asynchronous input enables the data I/O output drivers. G# is
the JEDEC-standard term for OE#.
SA0
SA1
SA
Input
Synchronous Address Inputs: These inputs are registered and must meet the setup and hold
times around the rising edge of CLK.
ZZ
Input
Snooze Enable: This active HIGH, asynchronous input causes the device to enter a low-power
standby mode in which all data in the memory array is retained. When ZZ is active, all other
inputs are ignored. This pin has an internal pull-down and can be left unconnected.

DESCRIPTION
ADSC#
Input Synchronous Address Status Controller: This active LOW input interrupts any ongoing burst,

independent of the byte write enables and ADSC#, but dependent upon CE#, CE2, and CE2#.
ADSP# is ignored if CE# is HIGH. Power-down state is entered if CE2 is LOW or CE2# is HIGH.
Input Synchcronous Address Advance: This active LOW input is used to advance the internal burst

BWs need to be asserted on the same cycle as the address. To enable the BW’s functionality, the
byte write enable (BWE#) input must be asserted LOW. BWa# controls DQa balls; BWb# controls
DQb balls; BWc# controls DQc balls; and BWd# controls DQa balls.
BWE#
CE#
Input
Byte Write Enable: This active LOW input permits BYTE WRITE operations and must meet the
setup and hold times around the rising edge of CLK.
Input Synchronous Chip Enable: This active LOW input is used to enable the device and conditions the
internal use of ADSP#. CE# is sampled only when a new external address is loaded.
CE2#
CE2
Input
Synchronous Chip Enable: This active LOW input is used to enable the device and is sampled only
when a new external address is loaded.
Input
Synchronous Chip Enable: This active HIGH input is used to enable the device and is sampled
only when a new external address is loaded.
CLK
Input Clock: This signal registers the address, data, chip enable, byte write enables, and burst control
inputs on its rising edge. All synchronous inputs must meet setup and hold times around the
clock’s rising edge.
GW#
Input
Global Write: This active LOW input allows a full 18-, 32-, or 36-bit WRITE to occur independent
of the BWE# and BWx# lines and must meet the setup and hold times around the rising edge of
CLK.
MODE (LBO#)
OE#(G#)
Input
Mode: This input selects the burst sequence. A LOW on this ball selects “linear burst.” NC or
HIGH on this ball selects “interleaved burst.” Do not alter input state while device is operating.
LBO# is the JEDEC-standard term for MODE.
Input Output Enable: This active LOW, asynchronous input enables the data I/O output drivers. G# is
the JEDEC-standard term for OE#.
SA0
SA1
SA
Input
Synchronous Address Inputs: These inputs are registered and must meet the setup and hold
times around the rising edge of CLK.

TDI
Input
IEEE 1149.1 test inputs: JEDEC-standard 3.3V or 2.5V I/O levels. These balls may be left as No
Connects if the JTAG function is not used in the circuit.
TCK
ZZ
Input Snooze Enable: This active HIGH, asynchronous input causes the device to enter a low-power
standby mode in which all data in the memory array is retained. When ZZ is active, all other
inputs are ignored. This ball has an internal pull-down and can be left unconnected.
DQa
DQb
DQc
DQd
Input/
SRAM Data I/Os: For the x18 version, byte “a” is associated with DQa pins; byte “b” is associated
Output with DQb balls. For the x32 and x36 versions, byte “a” is associated with DQa balls; byte “b” is
associated with DQb balls; byte “c” is associated with DQc balls; byte “d” is associated with DQd
balls. Input data must meet setup and hold times around the rising edge of CLK.

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 pins/balls and DQPa. BWb# enables WRITEs to DQb pins/balls and DQPb. BWc# enables
WRITEs to DQc pins/balls and DQPc. BWd# enables WRITEs to DQd pins/balls 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.

noted.
12. Measured as HIGH above VIH and LOW below VIL.
13. This parameter is measured with the output load-
ing shown in Figure 12 for 3.3V I/O and Figure 14
for 2.±V I/O.
14. Refer to Technical Note TN-±8-09, “Synchronous
SRAM Bus Contention Design Considerations,”
for a more thorough discussion of these parame-
ters.
1±. OE# is a “Don’t Care” when a byte write enable is
sampled LOW.
16. A WRITE cycle is defined by at least one byte write
(BWa#–BWd#) being LOW, the byte write enable
(BWE#) active, and ADSC# LOW for the required
setup and hold times. A READ cycle is defined by
the byte write enable (BWE#) being HIGH or
ADSP# LOW for the required setup and hold
times.
17. This is a synchronous device. All addresses must
meet the specified setup and hold times when
either ADSC# or ADSP# is LOW and chip is
enabled. All other synchronous inputs must meet
the setup and hold times with stable logic levels
for all rising edges of CLK when the chip is
enabled. To remain enabled, chip enable must be
valid at each rising edge when either ADSC# or
ADSP# is LOW.

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 ZZ 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.

IEEE 1149.1 Serial Boundary Scan (JTAG)
The SRAM incorporates a serial boundary scan test
access port (TAP). This port operates in accordance
with IEEE Standard 1149.1-1990 but does not have the
set of functions required for full 1149.1 compliance.
These functions from the IEEE specification are
excluded because their inclusion places an added
delay in the critical speed path of the SRAM. Note that
the TAP controller functions in a manner that does not
conflict with the operation of other devices using
1149.1 fully compliant TAPs. The TAP operates using
JEDEC-standard 3.3V or 2.±V I/O logic levels.
Test Access Port (TAP)
Test Clock (TCK)
The test clock is used only with the TAP controller.
All inputs are captured on the rising edge of TCK. All
outputs are driven from the falling edge of TCK.
Test MODE SELECT (TMS)
The TMS input is used to give commands to the TAP
controller and is sampled on the rising edge of TCK. It
is allowable to leave this ball unconnected if the TAP is
not used. The ball is pulled up internally, resulting in a
logic HIGH level.
The SRAM contains a TAP controller, instruction
register, boundary scan register, bypass register, and
ID register.
Test Data-In (TDI)
The TDI ball is used to serially input information
into the registers and can be connected to the input of
any of the registers. The register between TDI and TDO
is chosen by the instruction that is loaded into the TAP
instruction register. For information on loading the
instruction register, see Figure 1±. TDI is internally
pulled up and can be unconnected if the TAP is unused
in an application. TDI is connected to the most signifi-
cant bit (MSB) of any register. (See Figure 16.)
Disabling the JTAG Feature
These balls can be left floating (unconnected), if the
JTAG function is not to be implemented. Upon power-
up, the device will come up in a reset state which will
not interfere with the operation of the device.
Figure 15:
TAP Controller State Diagram
Test Data-Out (TDO)
TEST-LOGIC
1
The TDO output ball is used to serially clock data-
out from the registers. The output is active depending
upon the current state of the TAP state machine. (See
Figure 1±.) The output changes on the falling edge of
TCK. TDO is connected to the least significant bit
(LSB) of any register. (See Figure 16.)

PIPELINED, SCD SYNCBURST SRAM
The Boundary Scan Order tables show the order in
which the bits are connected. Each bit corresponds to
one of the bumps on the SRAM package. The MSB of
the register is connected to TDI, and the LSB is con-
nected to TDO.
Performing a TAP Reset
A RESET is performed by forcing TMS HIGH (VDD)
for five rising edges of TCK. This RESET does not affect
the operation of the SRAM and may be performed
while the SRAM is operating.
At power-up, the TAP is reset internally to ensure
that TDO comes up in a High-Z state.
Identification (ID) Register
The ID register is loaded with a vendor-specific, 32-
bit code during the Capture-DR state when the IDCO-
DEcommand is loaded in the instruction register. The
IDCODE is hardwired into the SRAM and can be
shifted out when the TAP controller is in the Shift-DR
state. The ID register has a vendor code and other
information described in the Identification Register
Definitions table.
TAP Registers
Registers are connected between the TDI and TDO
balls and allow data to be scanned into and out of the
SRAM test circuitry. Only one register can be selected
at a time through the instruction register. Data is seri-
ally loaded into the TDI ball on the rising edge of TCK.
Data is output on the TDO ball on the falling edge of
TCK.
TAP Instruction Set
Overview
Instruction Register
Three-bit instructions can be serially loaded into
the instruction register. This register is loaded when it
is placed between the TDI and TDO balls as shown in
Figure 16. Upon power-up, the instruction register is
loaded with the IDCODE instruction. It is also loaded
with the IDCODE instruction if the controller is placed
in a reset state as described in the previous section.
When the TAP controller is in the Capture-IR state,
the two least significant bits are loaded with a binary
“01” pattern to allow for fault isolation of the board-
level serial test data path.
Eight different instructions are possible with the
threebit instruction register. All combinations are
listed in the Instruction Codes table. Three of these
instructions are listed as RESERVED and should not be
used. The other five instructions are described in detail
below.
The TAP controller used in this SRAM is not fully
compliant to the 1149.1 convention because some of
the mandatory 1149.1 instructions are not fully imple-
mented.
The TAP controller cannot be used to load address,
data or control signals into the SRAM and cannot pre-
load the I/O buffers. The SRAM does not implement
the 1149.1 commands EXTEST or INTEST or the PRE-
LOAD portion of SAMPLE/PRELOAD; rather, it per-
forms a capture of the I/O ring when these instructions
are executed.
Instructions are loaded into the TAP controller dur-
ing the Shift-IR state when the instruction register is
placed between TDI and TDO. During this state,
instructions are shifted through the instruction regis-
ter through the TDI and TDO balls. To execute the
instruction once it is shifted in, the TAP controller
needs to be moved into the Update-IR state.
Bypass Register
To save time when serially shifting data through reg-
isters, it is sometimes advantageous to skip certain
chips. The bypass register is a single-bit register that
can be placed between the TDI and TDO balls. This
allows data to be shifted through the SRAM with mini-
mal delay. The bypass register is set LOW (VSS) when
the BYPASS instruction is executed.
Boundary Scan Register
The boundary scan register is connected to all the
input and bidirectional balls on the SRAM. The SRAM
has a 7±-bit-long register.
The boundary scan register is loaded with the con-
tents of the RAM I/O ring when the TAP controller is in
the Capture-DR state and is then placed between the
TDI and TDO balls when the controller is moved to the
Shift-DR state. The EXTEST, SAMPLE/PRELOAD and
SAMPLE Z instructions can be used to capture the
contents of the I/O ring.
EXTEST
EXTEST is a mandatory 1149.1 instruction which is
to be executed whenever the instruction register is
loaded with all 0s. EXTEST is not implemented in this
SRAM TAP controller, and therefore this device is not
compliant to1149.1. The TAP controller does recognize
an all-0 instruction.

PIPELINED, SCD SYNCBURST SRAM
When an EXTEST instruction is loaded into the
instruction register, the SRAM responds as if a SAM-
PLE/PRELOAD instruction has been loaded. There is
one difference between the two instructions. Unlike
the SAMPLE/PRELOAD instruction, EXTEST places
the SRAM outputs in a High-Z state.
the clock frequencies, it is possible that during the
Capture-DR state, an input or output will undergo a
transition. The TAP may then try to capture a signal
while in transition (metastable state). This will not
harm the device, but there is no guarantee as to the
value that will be captured. Repeatable results may not
be possible.
To guarantee that the boundary scan register will
capture the correct value of a signal, the SRAM signal
must be stabilized long enough to meet the TAP con-
troller’s capture setup plus hold time (tCS plus tCH).
The SRAM clock input might not be captured cor-
rectly if there is no way in a design to stop (or slow) the
clock during a SAMPLE/PRELOAD instruction. If this
is an issue, it is still possible to capture all other signals
and simply ignore the value of the CLK captured in the
boundary scan register.
Once the data is captured, it is possible to shift out
the data by putting the TAP into the Shift-DR state.
This places the boundary scan register between the
TDI and TDO balls.
Note that since the PRELOAD part of the command
is not implemented, putting the TAP to the Update-DR
state while performing a SAMPLE/PRELOAD instruc-
tion will have the same effect as the Pause-DR com-
mand.
IDCODE
The IDCODE instruction causes a vendor-specific,
32-bit code to be loaded into the instruction register. It
also places the instruction register between the TDI
and TDO balls and allows the IDCODE to be shifted
out of the device when the TAP controller enters the
Shift-DR state.
The IDCODE instruction is loaded into the instruc-
tion register upon power-up or whenever the TAP con-
troller is given a test logic reset state.
SAMPLE Z
The SAMPLE Z instruction causes the boundary
scan register to be connected between the TDI and
TDO balls when the TAP controller is in a Shift-DR
state. It also places all SRAM outputs into a High-Z
state.
SAMPLE/PRELOAD
SAMPLE/PRELOAD is a 1149.1 mandatory instruc-
tion. The PRELOAD portion of this instruction is not
implemented, so the device TAP controller is not fully
1149.1-compliant.
When the SAMPLE/PRELOAD instruction is loaded
into the instruction register and the TAP controller is in
the Capture-DR state, a snapshot of data on the inputs
and bidirectional balls is captured in the boundary
scan register.
The user must be aware that the TAP controller
clock can only operate at a frequency up to 10 MHz,
while the SRAM clock operates more than an order of
magnitude faster. Because there is a large difference in
BYPASS
When the BYPASS instruction is loaded in the
instruction register and the TAP is placed in a Shift-DR
state, the bypass register is placed between the TDI
and TDO balls. The advantage of the BYPASS instruc-
tion is that it shortens the boundary scan path when
multiple devices are connected together on a board.
