The ISSI IS61(64)LPS12832A, IS61(64)LPS/VP- S12836A and IS61(64)LPS/VPS25618A are high-speed, low-power synchronous static RAMs designed to provide burstable, high-performance memory for communication and networking applications. The IS61(64)LPS12832A is organized as 131,072 words by 32 bits. The IS61(64)LPS/ VPS12836A is organized as 131,072 words by 36 bits. The IS61(64)LPS/VPS25618A is organized as 262,144 words by 18 bits. Fabricated with ISSI's 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.
