Functional Description
The GS8162Z18(B/D)/36(B/D)/72(C) 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 GS8162Z18(B/D)/36(B/D)/72(C) 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 GS8162Z18(B/D)/36(B/D)/72(C) is implemented with
GSI's high performance CMOS technology and is available in
a JEDEC-standard 119-bump (x18 & x36), 165-bump (x18 &
x36), or 209-bump (x72) BGA package.
