Overview
¡¡SemicondSucetormiconductor MSC23B236A-xxBS8/DS8 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 72pin glass epoxy SIMM Package supports any application where high density and large capacity of storage memory are required.
