DRAM MODULE
KMM374F80(8)3CK3/CS3
KMM374F80(8)3CK3/CS3 EDO Mode without buffer
8M x 72 DRAM DIMM with ECC Using 8Mx8, 8K & 4K Refresh, 3.3V
GENERAL DESCRIPTION
The Samsung KMM374F80(8)3CK3/CS3 is a 8Mx72bits
Dynamic RAM high density memory module. The Samsung
KMM374F80(8)3CK3/CS3 consists of nine CMOS 8Mx8bits
DRAMs in SOJ/TSOP-II 400mil packages and one 2K
EEPROM for SPD in 8-pin SOP package mounted on a 168-
pin glass-epoxy substrate. A 0.1 or 0.22uF decoupling capaci-
tor is mounted on the printed circuit board for each DRAM.
The KMM374F80(8)3CK3/CS3 is a Dual In-line Memory Mod-
ule and is intended for mounting into 168 pin edge connector
sockets.
