DESCRIPTION
   The 4Mb product family features high-speed, low-power synchronous static RAMs designed to provide burstable, high-performance memory for communication and networking applications. The IS61(64)LPS/VPS12836EC are organized as 131,072 words by 36bits. The IS61(64)LPS/VPS12832EC are organized as 131,072 words by 32bits. The IS61(64)LPS/VPS25618EC are organized as 262,144 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 positiveedge-triggered single clock input.
