MSC23240D-xxBS20/DS20
2,097,152-word x 40-bit DYNAMIC RAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The MSC23240D-xxBS20/DS20 is a fully decoded, 2,097,152-word x 40-bit CMOS dynamic random access
memory module composed of twenty 4Mb DRAMs in SOJ packages mounted with twenty decoupling capacitors on
a 72-pin glass epoxy single-inline package. This module supports any application where high density and large
capacity of storage memory are required.
