GENERAL DESCRIPTION

The UT61L1024 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 UT61L1024 is designed for high-speed
system applications. It is particularly suited for use
in high-density high-speed system applications.

The UT61L1024 operates from a single 3.3V
power supply and all inputs and outputs are fully
TTL compatible.
