Functional Description
The GS8161ZxxB(T/D)-xxxV 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 GS8161ZxxB(T/D)-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.
The GS8161ZxxB(T/D)-xxxV is implemented with GSI's high
performance CMOS technology and is available in JEDEC-
standard 100-pin TQFP and 165-bump FP-BGA packages.
