4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM51V16405D/DSL is a 4,194,304-word
¥
4-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM51V16405D/DSL 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 MSM51V16405D/DSL is available in a 26/24-pin plastic SOJ
or 26/24-pin plastic TSOP. The MSM51V16405DSL (the self-refresh version) is specially designed
for lower-power applications.
