MSM51V4256A
DESCRIPTION
The MSM51V4256A is a 262,144-word
￥
4-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM51V4256A 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 MSM51V4256A is available in a 20-pin plastic DIP, 26/20-pin plastic SOJ,
or 20-pin plastic ZIP.
