DESCRIPTION

The ISSI IS61SF12832 and IS61SF12836 are high-speed synchronous static RAM designed to provide a burstable, high-performance memory for high speed networking and communication applications. It is organized as 131,072 words by 32 bits or 36 bits, fabricated with ISSIs advanced CMOS technology. The device integrates a 2-bit burst counter, high-speed 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.
