DESCRIPTION

The ICSI IC61SP12832,IC61SP12836 are high-speed, low power synchronous static RAM designed to provide a burstable, high-performance, secondary cache for the Pentium™, 680X0™, and PowerPC™ microprocessors. It is organized as 131,072 words by 32 bits, fabricated with ICSIs advanced CMOS technology. The device integrates a 2-bit burst counter, highspeed SRAM core, and high-drive capability outputs into a single monolithic circuit. All synchronous inputs pass through registers controlled by a positive-edge-triggered single clock input.
