DRAM MODULE  
KMM5322104CKU/CKUG  
KMM5322104CKU/CKUG Fast Page Mode with Extended Data Out  
2M x 32 DRAM SIMM using 2Mx8 , 2K Refresh, 5V  
GENERAL DESCRIPTION  
FEATURES  
The Samsung KMM5322104CKU is a 2Mx32bits Dynamic  
RAM high density memory module. The Samsung  
KMM5322104CKU consists of four CMOS 2Mx8bits DRAMs in  
28-pin SOJ package mounted on a 72-pin glass-epoxy sub-  
strate. A 0.1 or 0.22uF decoupling capacitor is mounted on the  
printed circuit board for each DRAM. The KMM5322104CKU is  
a Single In-line Memory Module with edge connections and is  
intended for mounting into 72 pin edge connector sockets.
