Functional Description
The GS8161Z18(T/D)/GS8161Z32(D)/GS8161Z36(T/D) is an
18Mbit 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 GS8161Z18(T/D)/GS8161Z32(D)/GS8161Z36(T/D) 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.
The GS8161Z18(T/D)/GS8161Z32(D)/GS8161Z36(T/D) is
implemented with GSI's high performance CMOS technology
and is available in JEDEC-standard 100-pin TQFP and
165-bump FP-BGA packages.
