MSM511000C/CL
1,048,576-Word ¥ 1-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
DESCRIPTION
The MSM511000C/CL is a 1,048,576-word ¥ 1-bit dynamic RAM fabricated in Oki's silicon-gate
CMOS technology. The MSM511000C/CL 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 MSM511000C/CL is available in a 26/20-pin plastic SOJ or
20-pin plastic ZIP. The MSM511000CL (the low-power version) is specially designed for lower-
power applications.
