Part Name(s) : MCM69T618 MCM69T618TQ5 MCM69T618TQ5R Motorola
Motorola => Freescale
Description : 64K x 18 Bit Synchronous Pipelined Cache Tag RAM View

The MCM69T618 is a 1M–bit Synchronous fast static RAM with integrated Tag compare function. It is designed to address Tag RAM for 512KB, 1MB, or 2MB secondary Cache as well as to be used as a data RAM for 512KB Caches. This device is organized as 64K words of 18 bits each. It integrates input registers, output registers, Tag comparators, and high speed SRAM onto a single monolithic circuit for reduced parts count in Cache Tag RAM applications. Synchronous design allows precise cycle control with the use of an external clock (K). BiCMOS circuitry reduces the overall power consumption of the integrated functions for greater reliability.

Description : BiCMOS StaticRAM 240K (16K x 15-BIT) Cache-Tag RAM For the Pentium™ Processor View

DESCRIPTION:
The IDT71215 is a 245,760-bit Cache Tag StaticRAM, organized 16K x 15 and designed to support the Pentium and other Intel processors at bus speeds up to 66MHz.
