The MCM63P837 and MCM63P919 are 8M–bit synchronous fast static RAMs
designed to provide a burstable, high performance, secondary cache for the
PowerPCTM and other high performance microprocessors. The MCM63P837
(organized as 256K words by 36 bits) and the MCM63P919 (organized as 512K
words by 18 bits) are fabricated in NXP’s high performance silicon gate
CMOS technology. Synchronous design allows precise cycle control with the use
of an external clock (K).
