256K x 72 18Mb Sync Burst SRAMs

Functional Description
Applications
The GS816272C is an 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.
