GENERAL DESCRIPTION
The AS7C164A is a 65,536-bit high speed CMOS static
random access memory organized as 8,192 words
by 8 bits. It is fabricated using very high
performance, high reliability CMOS technology. Its
standby current is stable within the range of
operating temperature.
The AS7C164A is well designed for high speed system
applications, and particularly well suited for battery
back-up nonvolatile memory application.
The AS7C164A operates from a single power supply
of 5V and all inputs and outputs are fully TTL
compatible
