The MCM63R836A/918A is an 8M–bit synchronous late write fast static RAM
designed to provide high performance in secondary cache and ATM switch,
Telecom, and other high speed memory applications. The MCM63R918A
(organized as 512K words by 18 bits) and the MCM63R836A (organized as
256K words by 36 bits) are fabricated in NXP’s high performance silicon gate
copper CMOS technology.
