REV. 0.1 Oct. 2000
M374F080(8)3DJ3-C EDO Mode without buffer
8M x 72 DRAM DIMM with ECC Using 8Mx8, 8K & 4K Refresh, 3.3V
The Samsung M374F080(8)3DJ3 is a 8Mx72bits Dynamic
RAM high density memory module. The Samsung
M374F080(8)3DJ3 consists of nine CMOS 8Mx8bits DRAMs
in SOJ 400mil packages and one 2K EEPROM for SPD in 8-
pin SOP package mounted on a 168-pin glass-epoxy sub-
strate. A 0.1 or 0.22uF decoupling capacitor is mounted on
the printed circuit board for each DRAM. The
M374F080(8)3DJ3 is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.
