MSM518205
4,194,304-Word ¥ 2-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM518205 is a 4,194,304-word ¥ 2-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM518205 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 MSM518205 is available in a 26/24-pin plastic SOJ or 26/24-pin plastic
TSOP.
