LY6164
Rev. 1.4
8K X 8 BIT HIGH SPEED CMOS SRAM
GENERAL DESCRIPTION
The LY6164 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 LY6164 is well designed for high speed system
applications, and particularly well suited for battery
back-up nonvolatile memory application.
The LY6164 operates from a single power supply
of 5V and all inputs and outputs are fully TTL
compatible
