1,048,576-Word ¥ 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM514400D/DL is a 1,048,576-word ¥ 4-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM514400D/DL 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 MSM514400D/DL is available in a 26/20-pin plastic SOJ, 20pin plastic ZIP, or 26/20-pin plastic TSOP. The MSM514400DL (the low-power version) is specially
designed for lower-power applications.
