MSM514400E/EL
1,048,576-Word x 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
Preliminary
DESCRIPTION
The MSM514400E/EL is a 1,048,576-word
×
4-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS
technology. The MSM514400E/EL achieves high integration, high-speed operation, and low-power consumption
because Oki manufactures the device in a quadruple-layer polysilicon/double-layer metal CMOS process. The
MSM514400E/EL is available in a 26/20-pin plastic SOJ, 26/20-pin plastic TSOP. The MSM514400EL (the
low-power version) is specially designed for lower-power applications.
