HDD16M64D8W
DDR SDRAM Module 128Mbyte (16Mx64bit), based on16Mx8,4Banks,
4K Ref., DIMM,
Part No. HDD16M64D8W
GENERAL DESCRIPTION
The HANBiT HDD16M64D8W is 16M bit x 64 Double Data Rate SDRAM high density memory modules. The HANBiT
HDD16M64D8W consists of eight CMOS 16M x 8 bit with 4banks Double Data Rate SDRAMs in 66pin TSOP-II(400mil) packages
mounted on a 184pin glass-epoxy substrate. Four 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel
for each DDR SDRAM. The HDD16M64D8W is Dual In-line Memory Modules and intended for mounting into 184pin edge
connector sockets. 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 allow the same device
to be useful for a variety of high bandwidth, high performance memory system applications.
