The MCM63P737A and MCM63P819A are 4M–bit synchronous fast static RAMs
designed to provide a burstable, high performance, secondary cache for the
PowerPCE and other high performance microprocessors. The MCM63P737A is
organized as 128K words of 36 bits each and the MCM63P819A is organized as
256K words of 18 bits each. These devices integrate input registers, an output
register, a 2–bit address counter, and high speed SRAM onto a single monolithic
circuit for reduced parts count in cache data RAM applications. Synchronous
design allows precise cycle control with the use of an external clock (K).
