GENERAL DESCRIPTION

The UT611024 is a 1,048,576-bit high speed
CMOS static random access memory organized
as 131,072 words by 8 bits. It is fabricated using
high performance, high reliability CMOS
technology.
The UT611024 is designed for high-speed system
application. It is particularly suited for use in high
speed and high density system applications.

The UT611024 operates from a signal 5V power
supply and all inputs and outputs are fully TTL
compatible
