MSC23409C/CL-xxDS9
4,194,304-Word ¥ 9-Bit DRAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The OKI MSC23409C/CL-xxDS9 is a fully decoded 4,194,304-word ¥ 9-bit CMOS Dynamic
Random Access Memory Module composed of nine 4-Mb DRAMs (4M ¥ 1) in SOJ packages
mounted with nine decoupling capacitors on a 30-pin glass epoxy single-inline package. This
module is generally used for memory expansion in parity applications such as workstations. The
low-power version (CL) offers reduced power consumption for mobile computing applications
like laptops and palmtops.
