DRAM MODULE KMM372V400CK/CS KMM372V410CK/CS KMM372V400CK/CS / KMM372V410CK/CS with Fast Page Mode 4M x 72 DRAM DIMM with ECC using 4Mx4, 4K & 2K Refresh , 3.3V GENERAL DESCRIPTION The Samsung KMM372V40(1)0C is a 4Mx72bits Dynamic RAM high density memory module. The Samsung KMM372V40(1)0C consists of eighteen CMOS 4Mx4bits DRAMs in SOJ/TSOP-II 300mil package, and two 16bits driver IC in 48pin TSSOP package mounted on a 168-pin glass- epoxy suCStrate. A 0.1 or 0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. The KMM372V40(1)0C is a Dual In-line Memory Module and is intended for mounting into 168 pin edge connector sockets.
