Functional Description

The GS880Z18/36AT is a 9Mbit 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.

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.

The GS880Z18/36AT may be configured by the user to

operate in Pipeline or Flow Through mode. Operating as a

pipelined synchronous device, meaning that 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.

The GS880Z18/36AT is implemented with GSI's high

performance CMOS technology and is available in a JEDEC-

Standard 100-pin TQFP package.
