DRAM MODULE
M372V320(8)0CJ4-C
Revision History
Version 0.0 (Jan. 1999)
The 4th. generation of 64M DRAM components are applied to this module.
DRAM MODULE
M372V320(8)0CJ4-C
M372V320(8)0CJ4-C Fast Page Mode
32M x 72 DRAM DIMM with ECC Using 16Mx4, 4K & 8K Refresh, 3.3V
The Samsung M372V320(8)0CJ4-C is a 32Mx72bits Dynamic
RAM high density memory module. The Samsung
M372V320(8)0CJ4-C 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
M372V320(8)0CJ4-C 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.
