GENERAL DESCRIPTION
The AS6C8008 is a 8,388,608-bit low power
CMOS static random access memory organized as
1,048,576 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 AS6C8008 is well designed for very low
power system applications, and particularly well
suited for battery back-up nonvolatile memory
application.
The AS6C8008 operates from a single power
supply of 2.7V ~ 5.5V and all inputs and outputs are
fully TTL compatible
