MSM514900C/CSL
This version: Jan. 1998
Previous version: May 1997
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.
