UT62L25616
256K X 16 BIT LOW POWER CMOS SRAM
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.
FEATURES
Fast access time : 55/70/100ns
