SEMICONDUCTOR TECHNICAL DATA

64K x 18 Bit Synchronous

Pipelined Cache Tag RAM

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 mono-

lithic 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.

isters. Data enable (DE) is sampled on the rising clock edge while output enable

can be loaded into the input register. The comparator compares the read data

with the registered input data, and a match signal is generated. The match output

is also stored by an output register and released to the match output buffer at the

next rising edge of clock (K).
