Functional Description

Applications

The GS8161E18B(T/D)/GS8161E32B(D)/GS8161E36B(T/D) is a 18,874,368-bit high performance synchronous SRAM with a 2-bit burst address counter. Although of a type originally developed for Level 2 Cache applications supporting high performance CPUs, the device now finds application in synchronous SRAM applications, ranging from DSP main store to networking chip set support.
