Description

The GS8321Z18/32/36E 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 GS8321Z18/32/36E is switched from read to write cycles.
Because GS8321Z18/32/36E 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 of GS8321Z18/32/36E 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. GS8321Z18/32/36E feature eliminates complex off-chip write pulse generation required by asynchronous SRAMs and simplifies input signal timing.

The GS8321Z18/32/36E 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 GS8321Z18/32/36E 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 GS8321Z18/32/36E is implemented with GSI's high performance CMOS technology and is available in JEDEC-standard 165-bump FP-BGA package.
