HANBit HDD16M72D9W DDR SDRAM Module 128Mbyte (16Mx72bit), based on 16Mx8, 4Banks 4K Ref., 184Pin-DIMM with Unbuffered ECC Part No. HDD16M72D9W GENERAL DESCRIPTION The HDD16M72D9W is a 64M x 72 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory module. The module consists of nine CMOS 16M 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 HDD16M72D9W 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.
