36Mb Pipelined and Flow Through

Synchronous NBT SRAM

1.8 V or 2.5 V V

1.8 V or 2.5 V I/O

Because it is a synchronous device, address, data inputs, and

read/ write control inputs are captured on the rising edge of the

input clock. Burst order control (LBO) must be tied to a power

rail for proper operation. Asynchronous inputs include the

Sleep mode enable, ZZ and Output Enable. Output Enable can

be used to override the synchronous control of the output

drivers and turn the RAM's output drivers off at any time.

Write cycles are internally self-timed and initiated by the rising

edge of the clock input. This feature eliminates complex off-

chip write pulse generation required by asynchronous SRAMs

and simplifies input signal timing.

Features

• User-configurable Pipeline and Flow Through mode

• NBT (No Bus Turn Around) functionality allows zero wait

read-write-read bus utilization

• Fully pin-compatible with both pipelined and flow through

NtRAM™, NoBL™ and ZBT™ SRAMs

• IEEE 1149.1 JTAG-compatible Boundary Scan

• 1.8 V or 2.5 V core power supply

• 1.8 V or 2.5 V I/O supply

• LBO pin for Linear or Interleave Burst mode

• Pin-compatible with 2Mb, 4Mb, 8Mb, and 18Mb devices

• Byte write operation (9-bit Bytes)

The GS8321Z18/32/36E-xxxV may be configured by the user

to operate in Pipeline or Flow Through mode. Operating as a

pipelined synchronous device, in addition to the rising-edge-

triggered registers that capture input signals, the device

incorporates a rising-edge-triggered output register. For read

cycles, pipelined SRAM output data is temporarily stored by

the edge triggered output register during the access cycle and

then released to the output drivers at the next rising edge of

clock.

• 3 chip enable signals for easy depth expansion

• ZZ pin for automatic power-down

• JEDEC-standard 165-bump FP-BGA package

• RoHS-compliant 165-bump BGA package available

Functional Description

The GS8321Z18/32/36E-xxxV is a 36Mbit Synchronous Static

SRAM. GSI's NBT SRAMs, like ZBT, NtRAM, NoBL or

other pipelined read/double late write or flow through read/

single late write SRAMs, allow utilization of all available bus

bandwidth by eliminating the need to insert deselect cycles

when the device is switched from read to write cycles.

The GS8321Z18/32/36E-xxxV is implemented with GSI's high

performance CMOS technology and is available in JEDEC-

standard 165-bump FP-BGA package.
