The MCM63F737K and MCM63F819K are 4M–bit synchronous fast static
RAMs designed to provide a burstable, high performance, secondary cache. The
MCM63F737K (organized as 128K words by 36 bits) and the MCM63F819K
(organized as 256K words by 18 bits) integrate input registers, 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).
