NEC Advanced Memory Buffer For FB-DIMMs


NEC announced that it has developed a new Advanced Memory Buffer (AMB) device
for use in fully buffered dual-inline memory modules (FB-DIMMs). Developed in
collaboration with Intel and fully compliant with the AMB standard ratified by
JEDEC, the AMB is a key enabling technology behind the increased bandwidths and
large memory capacities characteristic of emerging FB-DIMM products. The AMB
device helps bring new levels of memory performance to demanding applications
such as servers, routers and graphics controllers.

device helps bring new levels of memory performance to demanding applications
such as servers, routers and graphics controllers.

The AMB interface is responsible for handling FB-DIMM channel and memory
requests to and from the local DIMM and for forwarding the requests to other
DIMMs. Compared to existing registered DIMM technology, FB-DIMMs provide memory
capacities up to 24 times higher — 192GB vs. 8GB — and bandwidth up to four
times faster — 40GB/s vs. 10GB/s — when used with 1Gb x 4-bit DDRII-800 DRAM.
FB-DIMM technology also uses low-signal pins and only 69 pins per channel,
whereas existing DIMMs need 240 pins per channel.
