HANBit HDD128M72D18RPW 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 c ontrol with the use of system clock. Data I/O transactions are possible on both edges of DQS.
