GENERAL DESCRIPTION
The Samsung KMM5321204C2W is a 1Mx32bits Dynamic RAM high density memory module. The Samsung KMM5321204C2W consists of two CMOS 1Mx16bits DRAMs in 42-pin SOJ package 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 KMM5321204C2W is a Single In-line Memory Module with edge connections and is intended for mounting into 72 pin edge connector sockets.
