GENERAL DESCRIPTION

The UT62L25616 is a 4,194,304-bit low power CMOS

static random access memory organized as 262,144

words by 16 bits.

The UT62L25616 operates from a single 2.7V ~ 3.6V

power supply and all inputs and outputs are fully TTL

compatible.

The UT62L25616 is designed for low power system

applications. It is particularly suited for use in

high-density high-speed system applications.
