8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
The MSM5117805F is a 2,097,152-word
×
8-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS
technology. The MSM5117805F 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 MSM5117805F is available in a 28-pin plastic SOJ or 28-pin plastic TSOP.
