DRAM MODULE  
KMM372C160(8)0BK/BS  
KMM372C160(8)0BK/BS Fast Page Mode  
16M x 72 DRAM DIMM with ECC Using 16Mx4, 4K & 8K Refresh, 5V  
GENERAL DESCRIPTION  
FEATURES  
• Part Identification  
The Samsung KMM372C160(8)0B is a 16Mx72bits Dynamic  
RAM high density memory module. The Samsung  
KMM372C160(8)0B consists of eighteen CMOS 16Mx4bits  
DRAMs in SOJ/TSOP-II 400mil packages and two 16 bits  
driver IC in 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  
KMM372C160(8)0B 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 resistor 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.  
PD : 0 for Vol of Drive IC & 1 for N.C  
ID : 0 for Vss & 1 for N.C
