Functional Description
The GS882Z18/36A 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 GS882Z18/36A 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 GS882Z18/36A is implemented with GSI's high
performance CMOS technology and is available in JEDEC-
standard 119-bump BGA and 165-bump FPBGA packages.
