Functional Description
Applications
The GS840H18/32/36 is a 4,718,592 bit (4,194,304 bit for x32 version) 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 CPU’s, the device now finds application in synchronous SRAM applications ranging from DSP main store to networking chip set support. The GS840H18/32/36 is available in a JEDEC standard 100-lead TQFP or 119 Bump BGA package.
