KMM372E213CK/CS EDO Mode
2Mx72 DRAM DIMM with ECC using 2Mx8, 2K Refresh, 5V
The Samsung KMM372E213C is a 2Mx72bits Dynamic RAM
high density memory module. The Samsung KMM372E213C
consists of nine CMOS 2Mx8bits DRAMs in SOJ/TSOP-II
300mil package, and two 16bits driver IC in 48pin 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 KMM372E213C is a Dual In-line
Memory Module and is intended for mounting into 168-pin
edge connector sockets.
GENERAL DESCRIPTION
PD Note : PD & ID Terminals must each be pulled up through a register to V
CC
at the next higher
level assembly. PDs will be either open (NC) or driven to V
SS
via on-board buffer circuits.
ID Note : IDs will be either open (NC) or connected directly to V
SS
without a buffer.
