MSC23232D/DL-xxBS16/DS16
2,097,152-word x 32-bit DYNAMIC RAM MODULE : FAST PAGE MODE TYPE
DESCRIPTION
The MSC23232D/DL-xxBS16/DS16 is a fully decoded, 2,097,152-word x 32-bit CMOS dynamic random access
memory module composed of sixteen 4Mb DRAMs in SOJ packages mounted with sixteen 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. The MSC23232DL (the low-power version) is specially designed for
lower-power applications.
