KMM372F320(8)0CK3
KMM372F320(8)0CK3 EDO Mode
32M x 72 DRAM DIMM with ECC Using 16Mx4, 4K & 8K Refresh, 3.3V
GENERAL DESCRIPTION
The Samsung KMM372F320(8)0C is a 32Mx72bits Dynamic
RAM high density memory module. The Samsung
KMM372F320(8)0C consists of thirty-six CMOS 16Mx4bits
DRAMs in SOJ 400mil packages and two 16 bits driver IC in
TSSOP 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
KMM372F320(8)0C is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.

NOTE : A12 is used for only KMM372F3280CK3 (8K Ref.)
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.
PD : 0 for Vol of Drive IC & 1 for N.C
ID : 0 for Vss & 1 for N.C
ID Note : IDs will be either open (NC) or connected directly to V
SS
without a buffer.
