MSC23B236A-xxBS8/DS8
2,097,152-Word ¥ 36-Bit DRAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The Oki MSC23B236A-xxBS8/DS8 is a fully decoded 2,097,152-word ¥ 36-bit CMOS dynamic
random access memory composed of four 16-Mb (1M ¥ 16) DRAMs in SOJ and four 2-Mb (1M
¥ 2) DRAMs in SOJ. The mounting of eight DRAMs together with decoupling capacitors on a 72-
pin glass epoxy SIMM Package supports any application where high density and large capacity
of storage memory are required.
FEATURES
