Product Preview
64K x 18 Bit BurstRAMTM Synchronous Fast Static RAM
With Burst Counter and Self-Timed Write
The MCM67M618 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. It is organized as 65,536 words of 18 bits, fabricated
using Motorola's high-performance silicon-gate BiCMOS technology. The device inte-
grates input registers, a 2-bit counter, high speed SRAM, and high drive capability out-
puts 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).
