GS80 General Description
The GS882Z818/36B is an 8Mbit 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.
