16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
This version: August. 2002
Previous version : Sep..2001
DESCRIPTION
The MSM5116160F is a 1,048,576-word
×
16-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS
technology. The MSM5116160F 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 MSM5116160F is available in a 42-pin plastic SOJ or 50/44-pin plastic TSOP.
