This Hynix’s Fully Buffered DIMM is a high-bandwidth & large capacity channel solution that has a narrow

host interface. Hynix’s FB-DIMM features novel architecture including the Advanced Memory Buffer that

isolates the DDR2 SDRAMs from the channel. This single component located in the front side center of

each DIMM, acts as a repeater and buffer for all signals and commands which are exchanged between the

host 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.
