Description

Features

Block Diagram

The 4-megabit SRAM is a high-speed, super low-power CMOS SRAM organized as 256K

words by 16 bits. The SRAM uses high-performance full CMOS process technology and is

designed for high-speed and low-power circuit technology. It is particularly well-suited for the

high-density low-power system application. This device has a data retention mode that guar-

antees data to remain valid at a minimum power supply voltage of 1.2V.

• Fully Static Operation and Tri-state Output

• TTL Compatible Inputs and Outputs

• Battery Backup
