MSM512200/L
1,048,576-Word ¥ 2-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM512200/L is a 1,048,576-word ¥ 2-bit dynamic RAM fabricated in Oki's silicon-gate CMOS
technology. The MSM512200/L 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 MSM512200/L is available in a 26/20-pin plastic SOJ or 26/20-pin plastic
TSOP. The MSM512200L (the low-power version) is specially designed for lower-power applications.
FEATURES
• 1,048,576-word ¥ 2-bit configuration
