DESCRIPTION

The MSM5117400B is a 4,194,304-word ¥ 4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS

technology. The MSM5117400B achieves high integration, high-speed operation, and low-power

consumption because Oki manufactures the device in a quadruple-layer polysilicon/double-layer

metal CMOS process. The MSM5117400B is available in a 26/24-pin plastic SOJ or 26/24-pin plastic

TSOP.
