4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
The MSM51V16405F is a 4,194,304-word
×
4-bit dynamic RAM fabricated in Oki’s silicon-gate
CMOS technology. The MSM51V16405F 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 MSM51V16405F is available in a 26/24-pin plastic SOJ or 26/24-pin plastic
TSOP.
