Product Preview
64K x 18 Bit BurstRAMTM
Synchronous Fast Static RAM
With Burst Counter and Self-Timed Write
The MCM67B618 is a 1,179,648 bit synchronous fast static random access memory
designed to provide a burstable, high-performance, secondary cache for the i486 and
Pentium™ microprocessors. It is organized as 65,536 words of 18 bits, fabricated with
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).
