MSC23836C-xxBS20/DS20

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

This vers i on: Apr. 7. 1999

DESCRIPTION

The MSC23836C-x xBS20/DS20 is an 8,388,608-word x 36-bit CMOS dynam ic random access mem ory module
which is composed of sixteen 16Mb(4Mx4) DRAMs in SOJ packages and four 8Mb(4Mx2) DRAMs in SOJ packages
mounted with t wenty decoupl ing capaci tors. Thi s is a 72-pin si ngle i n-li ne mem ory m odule. Thi s modul e supports
any application where high density and large capacit y of storage memory are requi r ed.
