MSM514260C-70 Datasheet PDF - Oki Electric Industry

DESCRIPTION
The MSM514260C/CSL is a 262,144-word x 16-bit dynamic RAM fabricated in Okis silicon-gate CMOS technology. The MSM514260C/CSL achieves high integration, high-speed operation, and low-power consumption because Oki manufactures the device in a quadruple-layer polysilicon/single-layer metal CMOS process. The MSM514260C/CSL is available in a 40-pin plastic SOJ or 44/40-pin plastic TSOP. The MSM514260CSL (the self-refresh version) is specially designed for lowerpower applications.
