MSM514256CL Overview
The MSM514256C/CL is a 262,144-word ¥ 4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS technology. The MSM514256C/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 MSM514256C/CL is available in a 20-pin plastic DIP, 26/20-pin plastic SOJ, or 20-pin plastic ZIP.
