The MCM63F837 and MCM63F919 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 MCM63F837
(organized as 256K words by 36 bits) and the MCM63F919 (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).
