Improve FB-DIMM Performance
with IDT Advanced Memory Buffers
Advanced Memory Buffers, the next generation of FDIMM controllers, allow more DIMMS in a single
system, ideal for servers, workstations, storage devices and communication applications. The unique
channel structure of the IDT AMB chip alleviates buffer loading issues. The IDT AMB+ family offers
unparalleled power saving over standard AMB, which translates into a dramatic improvement in overall
cost and energy effi ciency.

The essential building block for next-generation,

The fully buffered dual in-line memory module (FB-DIMM) is the next generation memory architecture
to meet the growing memory requirement of servers and workstations. The IDT advanced memory buffer
(AMB) chip is the essential building block located on each FB-DIMM. The IDT AMB receives commands
and data from the host controller to control and write/read data to/from the DRAMs on the DIMM. Commands
and write data are sent southbound from the host controller to AMBs in a daisy chain fashion and interpreted
by the target AMB. Status and read data are sent northbound from AMBs to the host controller also in a daisy
chain fashion, passing through non-target AMBs. This unique channel structure alleviates buffer loading
issues common in registered DIMM technology, enabling designers to use a large number of DIMMs
within a single system. The IDT AMB complies with the latest JEDEC specifi cation for AMB and supports
DDR2-533/667/800 DRAM. It also enables serial data transfer at 3.2, 4.0 and 4.8 Gbps. The IDT AMB supports
servers, workstations, storage devices and communication applications that support the next generation
FB-DIMM architecture.
