SRAM with NoBL™ Architecture
18-Mbit (512
K × 36/1 M × 18) Pipelined SRAM with NoBL™ Architecture
Features
Functional Description
The CY7C1370D and CY7C1372D are 3.3 V, 512 K × 36 and
■ Pin-compatible and functionally equivalent to ZBT™
1 M × 18 synchronous pipelined burst SRAMs with No Bus
Latency™ (NoBL logic, respectively. They are designed to
support unlimited true back-to-back read/write operations with
no wait states. The CY7C1370D and CY7C1372D are equipped
with the advanced (NoBL) logic required to enable consecutive
read/write operations with data being transferred on every clock
cycle. This feature dramatically improves the throughput of data
in systems that require frequent write/read transitions. The
CY7C1370D and CY7C1372D are pin compatible and
functionally equivalent to ZBT devices.
■ Supports 250-MHz bus operations with zero wait states
❐ Available speed grades are 250, 200, and 167 MHz
■ Internally self-timed output buffer control to eliminate the need
to use asynchronous OE
■ Fully registered (inputs and outputs) for pipelined operation
■ Byte write capability
■ 3.3 V core power supply (VDD
)
All synchronous inputs pass through input registers controlled by
the rising edge of the clock. All data outputs pass through output
registers controlled by the rising edge of the clock. The clock
input is qualified by the clock enable (CEN) signal, which when
deasserted suspends operation and extends the previous clock
cycle.
■ 3.3 V/2.5 V I/O power supply (VDDQ
)
■ Fast clock-to-output times
❐ 2.6 ns (for 250 MHz device)
■ Clock enable (CEN) pin to suspend operation
■ Synchronous self-timed writes
Write operations are controlled by the byte write selects
(BWa–BWd for CY7C1370D and BWa–BWb for CY7C1372D)
and a write enable (WE) input. All writes are conducted with
on-chip synchronous self-timed write circuitry.
■ Available in JEDEC-standard Pb-free 100-pin TQFP, Pb-free
and non Pb-free 65-ball FBGA package
■ IEEE 1149.1 JTAG-compatible boundary scan
■ Burst capability – linear or interleaved burst order
■ “ZZ” sleep mode option and stop clock option
Three synchronous chip enables (CE1, CE2, CE3) and an
asynchronous output enable (OE) provide for easy bank
selection and output tri-state control. In order to avoid bus
contention, the output drivers are synchronously tristated during
the data portion of a write sequence.

Bidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the
synchronous rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by A[17:0]
during the previous clock rise of the read cycle. The direction of the pins is controlled by OE and the
internal control logic. When OE is asserted LOW, the pins can behave as outputs. When HIGH, DQa–DQd
are placed in a tristate condition. The outputs are automatically tristated during the data portion of a write
sequence, during the first clock when emerging from a deselected state, and when the device is deselected,
regardless of the state of OE.
DQPX
I/O-
Bidirectional data parity I/O lines. Functionally, these signals are identical to DQs. During write
synchronous sequences, DQPa is controlled by BWa, DQPb is controlled by BWb, DQPc is controlled by BWc, and

CY7C1370D
CY7C1372D
regardless of the state of chip enables inputs or WE. WE is
latched at the beginning of a burst cycle. Therefore, the type of
access (read or write) is maintained throughout the burst
sequence.
Functional Overview
The CY7C1370D and CY7C1372D are synchronous-pipelined
burst NoBL SRAMs designed specifically to eliminate wait states
during write/read transitions. All synchronous inputs pass
through input registers controlled by the rising edge of the clock.
The clock signal is qualified with the clock enable input signal
(CEN). If CEN is HIGH, the clock signal is not recognized and all
internal states are maintained. All synchronous operations are
qualified with CEN. All data outputs pass through output registers
controlled by the rising edge of the clock. Maximum access delay
from the clock rise (tCO) is 2.6 ns (250-MHz device).
Single Write Accesses
Write access are initiated when the following conditions are
satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2,
and CE3 are all asserted active, and (3) the write signal WE is
asserted LOW. The address presented is loaded into the
address register. The write signals are latched into the control
logic block.
Accesses can be initiated by asserting all three chip enables
(CE1, CE2, CE3) active at the rising edge of the clock. If clock
enable (CEN) is active LOW and ADV/LD is asserted LOW, the
address presented to the device will be latched. The access can
either be a read or write operation, depending on the status of
the write enable (WE). BWX can be used to conduct byte write
operations.
On the subsequent clock rise the data lines are automatically
tristated regardless of the state of the OE input signal. This
allows the external logic to present the data on DQ and DQP
(DQa,b,c,d/DQPa,b,c,d for CY7C1370D and DQa,b/DQPa,b for
CY7C1372D). In addition, the address for the subsequent
access (read/write/deselect) is latched into the address register
(provided the appropriate control signals are asserted).
Write operations are qualified by the write enable (WE). All writes
are simplified with on-chip synchronous self-timed write circuitry.
On the next clock rise the data presented to DQ and DQP
(DQa,b,c,d/DQPa,b,c,d for CY7C1370D & DQa,b/DQPa,b for
CY7C1372D) (or a subset for byte write operations, see Write
Cycle Description table for details) inputs is latched into the
device and the write is complete.
Three synchronous chip enables (CE1, CE2, CE3) and an
asynchronous output enable (OE) simplify depth expansion. All
operations (reads, writes, and deselects) are pipelined. ADV/LD
should be driven LOW once the device has been deselected in
order to load a new address for the next operation.
The data written during the write operation is controlled by BW
(BWa,b,c,d for CY7C1370D and BWa,b for CY7C1372D) signals.
The CY7C1370D/CY7C1372D provides byte write capability that
is described in the Write Cycle Description table. Asserting the
write enable input (WE) with the selected byte write select (BW)
input will selectively write to only the desired bytes. Bytes not
selected during a byte write operation will remain unaltered. A
synchronous self-timed write mechanism has been provided to
simplify the write operations. Byte write capability has been
included in order to greatly simplify read/modify/write
sequences, which can be reduced to simple byte write
operations.
Single Read Accesses
A read access is initiated when the following conditions are
satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2,
and CE3 are all asserted active, (3) the write enable input signal
WE is deasserted HIGH, and (4) ADV/LD is asserted LOW. The
address presented to the address inputs is latched into the
address register and presented to the memory core and control
logic. The control logic determines that a read access is in
progress and allows the requested data to propagate to the input
of the output register. At the rising edge of the next clock the
requested data is allowed to propagate through the output
register and onto the data bus within 2.6 ns (250-MHz device)
provided OE is active LOW. After the first clock of the read
access the output buffers are controlled by OE and the internal
control logic. OE must be driven LOW in order for the device to
drive out the requested data. During the second clock, a
subsequent operation (read/write/deselect) can be initiated.
Deselecting the device is also pipelined. Therefore, when the
SRAM is deselected at clock rise by one of the chip enable
signals, its output will tristate following the next clock rise.
Because the CY7C1370D and CY7C1372D are common I/O
devices, data should not be driven into the device while the
outputs are active. The output enable (OE) can be deasserted
HIGH before presenting data to the DQ and DQP
(DQa,b,c,d/DQPa,b,c,d for CY7C1370D and DQa,b/DQPa,b for
CY7C1372D) inputs. Doing so will tri-state the output drivers. As
a safety precaution, DQ and DQP (DQa,b,c,d/DQPa,b,c,d for
CY7C1370D and DQa,b/DQPa,b for CY7C1372D) are
automatically tristated during the data portion of a write cycle,
regardless of the state of OE.

The CY7C1370D/CY7C1372D has an on-chip burst counter that
allows the user the ability to supply a single address and conduct
up to four write operations without reasserting the address
inputs. ADV/LD must be driven LOW in order to load the initial
address, as described in the Single Write Accesses section
above. When ADV/LD is driven HIGH on the subsequent clock
rise, the chip enables (CE1, CE2, and CE3) and WE inputs are
ignored and the burst counter is incremented. The correct BW
(BWa,b,c,d for CY7C1370D and BWa,b for CY7C1372D) inputs
must be driven in each cycle of the burst write in order to write
the correct bytes of data.
The CY7C1370D and CY7C1372D have an on-chip burst
counter that allows the user the ability to supply a single address
and conduct up to four reads without reasserting the address
inputs. ADV/LD must be driven LOW in order to load a new
address into the SRAM, as described in the Single Read
Accesses section above. The sequence of the burst counter is
determined by the MODE input signal. A LOW input on MODE
selects a linear burst mode, a HIGH selects an interleaved burst
sequence. Both burst counters use A0 and A1 in the burst
sequence, and will wrap-around when incremented sufficiently.
A HIGH input on ADV/LD will increment the internal burst counter

Sleep Mode
Linear Burst Address Table
The ZZ input pin is an asynchronous input. Asserting ZZ places
the SRAM in a power conservation “sleep” mode. Two clock
cycles are required to enter into or exit from this “sleep” mode.
While in this mode, data integrity is guaranteed. Accesses
pending when entering the “sleep” mode are not considered valid
nor is the completion of the operation guaranteed. The device
must be deselected prior to entering the “sleep” mode. CE1, CE2,
and CE3, must remain inactive for the duration of tZZREC after the
ZZ input returns LOW.

CY7C1370D
CY7C1372D
IEEE 1149.1 Serial Boundary Scan (JTAG [17]
)
At power-up, the TAP is reset internally to ensure that TDO
comes up in a High Z state.
The CY7C1370D incorporates a serial boundary scan test
access port (TAP). This part is fully compliant with 1149.1. The
TAP operates using JEDEC-standard 3.3 V or 2.5 V I/O logic
levels.
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 serially loaded into the TDI ball on the
rising edge of TCK. Data is output on the TDO ball on the falling
edge of TCK.
The CY7C1370D contains a TAP controller, instruction register,
boundary scan register, bypass register, and ID register.
Disabling the JTAG Feature
It is possible to operate the SRAM without using the JTAG
feature. To disable the TAP controller, TCK must be tied LOW
(VSS) to prevent clocking of the device. TDI and TMS are
internally pulled up and may be unconnected. They may
alternately be connected to VDD through a pull-up resistor. TDO
should be left unconnected. Upon power-up, the device will
come up in a reset state which will not interfere with the operation
of the device.
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 the TAP Controller Block Diagram on
page 15. 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.
The 0/1 next to each state represents the value of TMS at the
rising edge of TCK.
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.
Test Access Port (TAP)
Bypass Register
Test Clock (TCK)
To save time when serially shifting data through registers, 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
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)
SRAM with minimal delay. The bypass register is set LOW (VSS
)
when the BYPASS instruction is executed.
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.
Boundary Scan Register
The boundary scan register is connected to all the input and
bidirectional balls on the SRAM.
Test Data-In (TDI)
The boundary scan register is loaded with the contents 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.
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. TDI is internally pulled
up and can be unconnected if the TAP is unused in an
application. TDI is connected to the most significant bit (MSB) of
any register.
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 connected to TDO.
Test Data-Out (TDO)
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. The output changes on the falling edge
of TCK. TDO is connected to the least significant bit (LSB) of any
register.
Identification (ID) Register
The ID register is loaded with a vendor-specific, 32-bit code
during the Capture-DR state when the IDCODE command 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.
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.
Note
17. Errata: The JTAG testing should be performed with these devices in BYPASS mode as the JTAG functionality is not guaranteed. For more information, see “Errata”

there is no guarantee as to the value that will be captured.
Repeatable results may not be possible.
TAP Instruction Set
Overview
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 controller’s capture setup plus hold
times (tCS and tCH). The SRAM clock input might not be captured
correctly 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 CK and CK captured in the boundary scan register.
Eight different instructions are possible with the three bit
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.
Instructions are loaded into the TAP controller during the Shift-IR
state when the instruction register is placed between TDI and
TDO. During this state, instructions are shifted through the
instruction register 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.
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 pins.
PRELOAD allows an initial data pattern to be placed at the
latched parallel outputs of the boundary scan register cells prior
to the selection of another boundary scan test operation.
EXTEST
The EXTEST instruction enables the preloaded data to be driven
out through the system output pins. This instruction also selects
the boundary scan register to be connected for serial access
between the TDI and TDO in the shift-DR controller state.
The shifting of data for the SAMPLE and PRELOAD phases can
occur concurrently when required – that is, while data captured
is shifted out, the preloaded data can be shifted in.
BYPASS
IDCODE
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 instruction is that it shortens the boundary scan path
when multiple devices are connected together on a board.
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 instruction register
upon power-up or whenever the TAP controller is given a test
logic reset state.
EXTEST Output Bus Tristate
IEEE Standard 1149.1 mandates that the TAP controller be able
to put the output bus into a tristate mode.
SAMPLE Z
The boundary scan register has a special bit located at bit #85
(for 119-ball BGA package) or bit #89 (for 165-ball FBGA
package). When this scan cell, called the “extest output bus
tristate,” is latched into the preload register during the
“Update-DR” state in the TAP controller, it will directly control the
state of the output (Q-bus) pins, when the EXTEST is entered as
the current instruction. When HIGH, it will enable the output
buffers to drive the output bus. When LOW, this bit will place the
output bus into a High Z condition.
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 instruction. When
the SAMPLE/PRELOAD instructions are loaded into the
instruction register and the TAP controller is in the Capture-DR
state, a snapshot of data on the inputs and output pins is
captured in the boundary scan register.
This bit can be set by entering the SAMPLE/PRELOAD or
EXTEST command, and then shifting the desired bit into that cell,
during the “Shift-DR” state. During “Update-DR,” the value
loaded into that shift-register cell will latch into the preload
register. When the EXTEST instruction is entered, this bit will
directly control the output Q-bus pins. Note that this bit is preset
HIGH to enable the output when the device is powered-up, and
also when the TAP controller is in the “Test-Logic-Reset” state.
The user must be aware that the TAP controller clock can only
operate at a frequency up to 20 MHz, while the SRAM clock
operates more than an order of magnitude faster. Because there
is a large difference in 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

These instructions are not implemented but are reserved for
future use. Do not use these instructions.

Description
Device
Fix Status
1. ZZ Pin
When asserted HIGH, the ZZ pin places
deviceina“sleep”conditionwithdataintegrity
preserved.The ZZ pin currently does not have
an internal pull-down resistor and hence
cannot be left floating externally by the user
during normal mode of operation.
18M-Ram9 (90nm)
For the 18M Ram9 (90 nm)
devices, there is no plan to fix
this issue.
2. JTAG
During JTAG test mode, the Boundary scan
18M-Ram9 (90nm)
This issue will be fixed in the
new revision, which use the
65 nm technology. Please
contact your local sales rep for
availability.
Functionality circuitry does not perform as described in the
datasheet.However, it is possible to perform
the JTAG test with these devices in “BYPASS
mode”.

CY7C1370D
CY7C1372D
1. ZZ Pin Issue
■ PROBLEM DEFINITION
The problem occurs only when the device is operated in the normal mode with ZZ pin left floating. The ZZ pin on the SRAM
device does not have an internal pull-down resistor. Switching noise in the system may cause the SRAM to recognize a HIGH
on the ZZ input, which may cause the SRAM to enter sleep mode. This could result in incorrect or undesirable operation of the
SRAM.
■ TRIGGER CONDITIONS
Device operated with ZZ pin left floating.
■ SCOPE OF IMPACT
When the ZZ pin is left floating, the device delivers incorrect data.
■ WORKAROUND
Tie the ZZ pin externally to ground.
■ FIX STATUS
For the 18M Ram9 (90 nm) devices, there is no plan to fix this issue.
2. JTAG Functionality
■ PROBLEM DEFINITION
The problem occurs only when the device is operated in the JTAG test mode.During this mode, the JTAG circuitry can perform
incorrectly by delivering the incorrect data or the incorrect scan chain length.
■ TRIGGER CONDITIONS
Several conditions can trigger this failure mode.
1. The device can deliver an incorrect length scan chain when operating in JTAG mode.
2. Some Byte Write inputs only recognize a logic HIGH level when in JTAG mode.
3. Incorrect JTAG data can be read from the device when the ZZ input is tied HIGH during JTAG operation.
■ SCOPE OF IMPACT
