8,388,608-wo rd x 36-bit DYNAMIC RAM MODULE : FAST PAGE MODE TYPE

This vers i on: Mar. 8. 1999

DESCRIPTION

The MSC23836D-xxBS20/DS20 is a fully decoded, 8,388,608-word x 36-bit CMOS dynamic random access
memory module composed of sixteen 16Mb DRAMs (4Mx4) in SOJ packages and four 8Mb DRAMs (4Mx2) in SOJ
packages mounted with t wenty decoupl i ng c apaci tors on a 72-pi n gl ass epoxy singl e in- li ne pack age. T his m odule
supports any applicat ion where high density and l ar ge c apac ity of stor age memory ar e r equired.
