4,194,304-Word × 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
The MSM51V17405F is a 4,194,304-word × 4-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS technology.
The MSM51V17405F achieves high integration, high-speed operation, and lowpower consumption because Oki manufactures the device in a quadruple-layer polysilicon/double-layer metal CMOS process.
The MSM51V17405F is available in a 26/24-pin plastic SOJ or 26/24-pin plastic TSOP.
