DESCRIPTION
The ISSI IS61VPS51232, IS61VPS51236, and IS61VPS10018 are high-speed, low-power synchronous static RAMs designed to provide burstable, high-performance memory for communication and networking applications. The IS61VPS51232is organized as 524,288 words by 32 bits and the IS61VPS51236 is organized as 524,288 words by 36 bits. The IS61VPS10018 is organized as 1,048,576 words by 18 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-edgetriggered single clock input.
