GSI Technology GS841Z36AT
The GS841Z18/36AT may be configured by the user to operate in Pipeline or Flow Through mode. 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 GS841Z18/36AT is implemented with GSI's high performance CMOS technology and is available in a JEDECStandard 100-pin TQFP package.FEATURES

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.
