GENERAL DESCRIPTION

The AS6C62256 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 AS6C62256 is well designed for low power

application, and particularly well suited for battery

back-up nonvolatile memory application.

The AS6C62256 operates with wide range power

supply 2.7 ~ 5.5V

.
