DRAM MODULE
KMM372C213CK/CS Fast Page Mode
2M x 72 DRAM DIMM with ECC using 2Mx8, 2K Refresh , 5V
GENERAL DESCRIPTION
The Samsung KMM372C213C is a 2Mx72bits Dynamic RAM
high density memory module. The Samsung KMM372C213C
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 cir-
cuit board for each DRAM. The KMM372C213C is a Dual In-
line Memory Module and is intended for mounting into 168 pin
edge connector sockets.

PD Note : PD & ID Terminals must each be pulled up through a resister 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.
PD : 0 for Vol of Drive IC & 1 for N.C
ID Note : IDs will be either open (NC) or connected directly to V
SS
without a buffer.
ID : 0 for Vss & 1 for N.C
