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.
