524,288-Word ¥ 9-Bit DYNAMIC RAM : FAST PAGE MODE TYPE

DESCRIPTION

The MSM514900C/CSL is a 524,288-word ¥ 9-bit dynamic RAM fabricated in Oki's silicon-gate

CMOS technology. The MSM514900C/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 MSM514900C/CSL is available in a 28-pin plastic SOJ or 28-

pin plastic TSOP. The MSM514900CSL (the self-refresh version) is specially designed for lower-

power applications.

FEATURES

• 524,288-word ¥ 9-bit configuration
