UT621024
128K X 8 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The UT621024 is a 1,048,576-bit low power
CMOS static random access memory
organized as 131,072 words by 8 bits. It is
fabricated using high performance, high
reliability CMOS technology.
The UT621024 is designed for low power
application. It is particularly well suited for
battery back-up nonvolatile memory
application.
The UT621024 operates from a single 5V
power supply and all inputs and outputs are
fully TTL compatible.
