A-Data Technology, one of the world’s largest makers of memory modules, announced its FB-DIMM products designed for high-end servers. The company said its memory modules have been validated by several server makers and will be commercially supplied in early 2006.

The lineup of FB-DIMM products A-Data can provide includes 512MB, 1GB and 2GB modules as well as 533MHz and 667MHz clock-speeds. The firm said that it uses Advanced Memory Buffer (AMB) chips from Intel, Integrated Device Technology (IDT) and NEC. Memory chips for FB-DIMMs were supplied by Samsung, Elpida and Hynix.

“A-Data has offered FB-DIMMs for tests and reviews and has passed many server/workstation manufacturers’ tests in both PC2-5300F (667MHz, CL5-5-5) PC2-4300F (667MHz, CL4-4-4) modes,” the company said in a statement.

A-Data FB-DIMMs will initially target server platforms with up to eight DIMM slots. According to Intel, FB-DIMM technology will provide systems with support of up to 192GB of memory through six channels, eight modules per channel and 4GB per module incorporating 1Gb DRAM devices.

FB-DIMMs utilizes typical DDR2 SDRAM chips, but the modules’ design is completely new: in the FB-DIMM, all signals – clock, address, command and data – to and from the DRAM on the module are buffered at the high-speed Advanced Memory Buffer (AMB) chip located on the DIMM. This helps to secure the DRAM timing margins during high-speed operation with a much shorter signal path between the DRAM and the AMB.
