262,144-Word ¥ 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM514260C/CSL is a 262,144-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM514260C/CSL 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 MSM514260C/CSL is available in a 40-pin plastic SOJ or 44/
40-pin plastic TSOP. The MSM514260CSL (the self-refresh version) is specially designed for lowerpower applications.
