64K x 18 Bit BurstRAMTM
Synchronous Fast Static RAM
With Burst Counter and Self-Timed Write
The MCM67H618 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
Pentiumâ„¢ microprocessors. It is organized as 65,536 words of 18 bits, fabricated with
Motorola's high-performance silicon-gate Bi
CMOS 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). Bi
CMOS circuitry reduces the overall power consumption of the
integrated functions for greater reliability.
Addresses (AO - A15), data inputs (DO - 017), and all control signals except
output enable (G) are clock (K)...
