Samsung serves up 8GB memory modules
Samsung has built an 8GB fully buffered memory module for servers - said to be the highest capacity DIMM designed for server use.
The monster module packs in 32 80nm 2Gb DDR 2 SDRAM devices - 16 on each side - along with the Advanced Memory Buffer (AMB) chip that allows the FB-DIMMs to be daisy-chained together across a two-way, point-to-point serial bus developed by Intel.
All instructions sent to a given FB-DIMM's memory chips to read or write data are stored and then forwarded by each DIMM ahead of it in the chain. The memory addresses and the clock timings are buffered too. Data is sent back and forth in packets, co-ordinated by the DIMMs' AMB chips, eliminating errors and signal interference.
Samsung didn't say when the 8GB modules would go on sale. ®
