GENERAL DESCRIPTION
The AS6C2008A is a 2,097,152-bit low power
CMOS static random access memory organized as
262,144 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 AS6C2008A is well designed for very low power
system applications, and particularly well suited for
battery back-up nonvolatile memory application.
The AS6C2008A operates from a single power
supply of 2.7V ~ 5.5V and all outputs are fully TTL
compatible
