The MCM63P737K and MCM63P819K are 4M–bit synchronous fast static
RAMs designed to provide a burstable, high performance, secondary cache. The
MCM63P737K (organized as 128K words by 36 bits) and the MCM63P819K
(organized as 256K words by 18 bits) 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 al-lows
precise cycle control with the use of an external clock (K).
