524,288-Word
¥
8-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
The MSM514800C/CSL is a 524,288-word
¥
8-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM514800C/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 MSM514800C/CSL is available in a 28-pin plastic SOJ or 28-
pin plastic TSOP. The MSM514800CSL (the self-refresh version) is specially designed for lower-
power applications.
