GENERAL DESCRIPTION
The LY62256 is a 262,144-bit low power CMOS
static random access memory organized as 32,768
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 LY62256 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The LY62256 operates from a single power
supply of 2.7~5.5V and all inputs and outputs are
fully TTL compatible
