HYMP125F72CP8N3-Y5 - Hynix 2GB DDR2 DDR2-667MHz PC2-5300 ECC Fully Buffered CL5 240-Pin DIMM Dual Rank Memory Module

This SK Hynixs Fully Buffered DIMM is a high-bandwidth & large capacity channel solution that has a narrowhost interface. Hynixs FB-DIMM features novel architecture including the Advanced Memory Buffer that is olates the DDR2 SDRAMs from the channel. This single component located in the front side center ofeach DIMM, acts as a repeater and buffer for all signals and commands which are exchanged between thehost controller and the DDR2 SDRAMs including data in and output. The AMB communicates with the host controller and adjacent DIMMs on a system board using an industry standard Differential Point to Point Link Interface at 1.5V power. The AMB also allows buffering of memory traffic to support large memory capacities. All memory control for the DDR2 SDRAM devices resides in the host, including memory request initiation, timing, refresh, scrubbing, sparing, configuration access and power management. The AMB interface is responsible for handling channel and memory requests to and from the local FBDIMM and for forwarding request to other FBDIMMs on the memory channel.
