16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE (BYTE WRITE)
DESCRIPTION
The MSM511664C/CL is a 65,536-word
¥
16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM511664C/CL 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 MSM511664C/CL is available in a 40-pin plastic SOJ or 44/40-pin plastic
TSOP. The MSM511664CL (the low-power version) is specially designed for lower-power applications.
