DDR SDRAM Module 1024Mbyte (128Mx72bit), based on 64Mx8, 4Banks,  
8K Ref., 184Pin-DIMM with PLL & Register Part No. HDD128M72D18RPW  
GENERAL DESCRIPTION  
The HDD128M72D18RPW is a 128M x 72 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory  
module. The module consists of eighteen CMOS 64M x 8 bit with 4banks DDR SDRAMs in 66pin TSOP-II 400mil packages  
and 2K EEPROM in 8-pin TSSOP package on a 184-pin glass-epoxy. Four 0.1uF decoupling capacitors are mounted on  
the printed circuit board in parallel for each DDR SDRAM. The HDD128M72D18RPW is a DIMM( Dual in line Memory  
Module) .Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible  
on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allows the same device  
to be useful for a variety of high bandwidth, high performance mem ory system applications. All module components may be  
powered from a single 2.5V DC power supply and all inputs and outputs are SSTL_2 compatible.
