Benefits

The benefits of FB-DIMM architecture include

• Higher performance

• Improved reliability

Simplified board design

FB-DIMMs use a 240-pin socket similar to that used for traditional DDR2 registered DIMMs; however,

FB-DIMMs require significantly fewer signal traces. FB-DIMMs have 69 signal traces compared to 138

traces for DDR2 registered DIMMs. These traces have to be routed to every DDR2 DIMM on the

channel, which complicates board design. FB-DIMMs have additional traces for the secondary links

between sockets, but these traces do not add to overall routing complexity.

In addition, the memory controller and AMB can compensate for signal traces of unequal length, thus

eliminating the need for odd routing paths to make sure the timing is correct. The lower number of

signal traces and the ability to use traces of unequal length greatly simplify board design for FB-

DIMMs.

Higher memory capacity

The point-to-point FB-DIMM architecture enables the electrical load (and signal integrity) for each

channel to remain constant, even as FB-DIMMs are added. This allows system designers to have up to

8 DIMMs per channel (no rank limits) while maintaining a low soft error rate (Figure 5). In

comparison, PC2-3200 SDRAM can have a maximum of 2 dual-rank DIMMs (or 4 single-rank

DIMMs) per channel

Figure 5. The FB-DIMM architecture allows up to 8 FB-DIMM sockets per channel.
