262,144-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
The MSM5416258A is a 262,144-word ¥ 16-bit dynamic RAM fabricated in Oki's CMOS silicon gate
technology. The MSM5416258A 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 MSM5416258A is available in a 44/40-pin plastic TSOP.
