The MCM67M618B is a 1,179,648–bit synchronous static random access
memory designed to provide a burstable, high–performance, secondary cache
for the MC68040 and PowerPCTM microprocessors. The MCM67M618B
(organized as 65,536 words by 18 bits) is fabricated using Motorola’s high–performance
silicon–gate BiCMOS technology. The device integrates input registers,
a 2–bit counter, high speed SRAM, and high drive capability outputs onto
a single monolithic circuit for reduced parts count implementation of cache data
RAM applications. Synchronous design allows precise cycle control with the use
of an external clock (K). BiCMOS circuitry reduces the overall power con-sumption
of the integrated functions for greater reliability.
