DRAM MODULE
M374F0805DT1-C
REV. 0.1 Oct. 2000
M374F0805DT1-C Fast EDO Mode without buffer
8M x 72 DRAM DIMM with ECC Using 4Mx16 & 4Mx4, 4K Refresh, 3.3V
The Samsung M374F0805DT1-C is a 8Mx72bits Dynamic
RAM high density memory module. The Samsung
M374F0805DT1-C consists of eight CMOS 4Mx16bits
DRAMs in TSOP 400mil packages and four CMOS 4Mx4bits
DRAMs in TSOP 300mil package and one 2K EEPROM for
SPD in 8-pin TSSOP package mounted on a 168-pin glass-
epoxy substrate. A 0.1 or 0.22uF decoupling capacitor is
mounted on the printed circuit board for each DRAM. The
M374F0805DT1-C is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.
