Integrated Device Technology Inc. (IDT) announced it is the main advanced memory buffer (AMB) supplier for Elpida Memory Inc.'s family of fully-buffered DIMM (FB-DIMM) products.

Targeting next-generation server and workstation applications, the Elpida family of FB-DIMM devices (512Mbit, 1Gbit, 2Gbit and 4 Gbit) is shipping with the IDT AMB device.

The IDT AMB (IDTAMB0480A5R) is responsible for collecting and distributing the data from or to the FB-DIMMs, buffering the data internally on the chip and receiving or forwarding it to the next FB-DIMM or memory controller within the system. According to IDT, this unique channel structure alleviates electrical loading issues, enabling designers to use a large number of DIMMs within a single system. To this point, Elpida has succeeded in developing a 4Gbyte FB-DIMM, allowing for a 64Gbyte (16 x 4Gbyte FB-DIMM) server memory architecture, which the IDT AMB can support.

Both the Elpida FB-DIMMs and IDT AMB support the Intel Dual-Core Xeon Processor Series 5000 and 5100 (formerly codenamed Dempsey and Woodcrest), which are targeted at server and workstation applications.

"The IDT AMB device is a proven technology, as demonstrated through the Intel validation process," said Shigeru Koshimaru, executive officer, server and PC division, Elpida. "In addition, the product offers a variety of innovative functions, including a thermal sensor necessary for high-capacity FB-DIMMs."
