MSM512805C

DESCRIPTION

The MSM512805C is a 262,144-word ¥ 8-bit dynamic RAM fabricated in Oki's silicon-gate CMOS

technology. The MSM512805C achieves high integration, high-speed operation, and low-power

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

metal CMOS process. The MSM512805C is available in a 26/24-pin plastic SOJ or 26/24-pin plastic

TSOP.
