MSC2313258A-xxBS2/DS2
MSC2313258A-xxBS2/DS2
1,048,576-Word ¥ 32-Bit DRAM MODULE : FAST PAGE MODE TYPE WITH EDO
DESCRIPTION
1
The Oki MSC2313258A-xxBS2/DS2 is a fully decoded 1,048,576-word ¥ 32-bit CMOS dynamic
random access memory composed of two 16-Mb (1M ¥ 16) DRAMs in SOJ. The mounting of two
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.
