MSM514265C/CSL

DESCRIPTION

The MSM514265C/CSL is a 262,144-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate

CMOS technology. The MSM514265C/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 MSM514265C/CSL is available in a 40-pin plastic SOJ or 44/

40-pin plastic TSOP. The MSM514265CSL (the self-refresh version) is specially designed for lower-

power applications.
