DESCRIPTION

The MSM51V17405D/DSL is a 4,194,304-wordx4-bit dynamic RAM fabricated in Okis silicon-gate CMOS technology. The MSM51V17405D/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 MSM51V17405D/DSL is available in a 26/24-pin plastic SOJ or 26/24-pin plastic TSOP. The MSM51V17405DSL (the self-refresh version) is specially designed for lower-power applications.
