MSM514256C/CL
This version: Jan. 1998
Previous version: May 1997
DESCRIPTION
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. The MSM514256CL (the low-power version) is specially designed for
lower-power applications.
