256Kx16 LP SRAM EM6156K600V Series

1

DCC-SR-041003-A

GENERAL DESCRIPTION

The EM6156K600V is a 4,194,304-bit low power CMOS static random access memory organized as

262,144 words by 16 bits. It is fabricated using very high performance, high reliability CMOS

technology. Its standby current is stable within the range of operating temperature.

The EM6156K600V is well designed for low power application, and particularly well suited for battery

back-up nonvolatile memory application.

The EM6156K600V operates from a single power supply of 2.7V ~ 3.6V and all inputs and outputs are

fully TTL compatible
