DRAM MODULE
GENERAL DESCRIPTION
The Samsung KMM372C80(8)3C is a 8Mx72bits Dynamic
RAM
KMM372C80(8)3C consists of nine CMOS 8Mx8bits DRAMs
in SOJ/TSOP-II 400mil packages and two 16 bits driver IC in
TSSOP package mounted on a 168-pin glass-epoxy sub-
strate. A 0.1 or 0.22uF decoupling capacitor is mounted on
the
KMM372C80(8)3C is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.
