GENERAL DESCRIPTION
The Samsung KMM332F804B is a 8Mx32bits Dynamic RAM high density memory module. The Samsung KMM332F804B consists of four CMOS 4Mx16bits DRAMs in TSOPII packages mounted on a 72-pin zigzag glass-epoxy substrate. A 0.1 or 0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. The KMM332F804B is a Small Out-line Dual In-line Memory Module with edge connections and is intended for mounting into 72-pin dual readout zigzag edge connector sockets.
