4M x 32 DRAM SIMM Using 4Mx16, 4K Refresh, 5V
GENERAL DESCRIPTION
The Samsung KMM5324000B is a 4Mx32bits Dynamic RAM
high density memory module. The Samsung KMM5324000B
consists of two CMOS 4Mx16bits DRAMs in TSOP packages
mounted on a 72-pin glass-epoxy substrate. A 0.1 or 0.22uF
decoupling capacitor is mounted on the printed circuit board
for each DRAM. The KMM5324000B is a Single In-line Mem-
ory Module with edge connections and is intended for mount-
ing into 72 pin edge connector sockets.
