M53230224DE2 Datasheet | Samsung Semiconductor

DESCRIPTION The Samsung M53230224D is a 2Mx32bits Dynamic RAM high density memory module. The Samsung M53230224D consists of four CMOS 1Mx16bits DRAMs in 42-pin SOJ package mounted on a 72-pin glass-epoxy substrate. A 0.1 or 0.22u F decoupling capacitor is mounted on the printed circuit board for each DRAM. The M53230224D is a Single In-line Memory Module with edge connections and is intended for mounting into 72 pin edge connector sockets.
