´
4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
This version:Apr.1999
DESCRIPTION
The MSM5116400D is a 4,194,304-word
´
4-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS
technology. The MSM5116400D achieves high integration, high-speed operation, and low-power consumption
because Oki manufactures the device in a quadruple-layer polysilicon/double-layer metal CMOS process. The
MSM5116400D is available in a 26/24-pin plastic SOJ, 26/24-pin plastic TSOP.
