¥
4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MD51V64405 is a 16,777,216-word
¥
4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MD51V64405 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 MD51V64405 is available in a 32-pin plastic SOJ or 32-pin plastic TSOP.
