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.
FEATURES
