The ISSI IS61LV6464 is a high-speed, low-power synchronous static RAM designed to provide a burstable, highperformance, secondary cache for the PentiumTM, 680X0TM, and PowerPCTM microprocessors. It is organized as 65,536 words by 64 bits, fabricated with ISSI's 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.
