This version: Mar. 1998 MD51V65165
4,194,304-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MD51V65165 is a 4,194,304-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MD51V65165 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 MD51V65165 is available in a 50-pin plastic SOJ or 50-pin plastic TSOP.
FEATURES
