GENERAL DESCRIPTION
The UT6164C is a 65,536-bit high-speed CMOS
static random access memory organized as 8,192
words by 8 bits. It is fabricated using high
performance, high reliability CMOS technology.
The UT6164C is designed for high-speed system
applications. It is particularly suited for use in
high-density high-speed system applications.
The UT6164C operates from a single 5V power
supply and all inputs and outputs are fully TTL
compatible.
