JEDEC-compliant memory buffer for DDR3 LRDIMM

Integrated Device Technology has introduced JEDEC-compliant Memory Buffer for DDR3 (MB3). The IDT MB301L has been designed for use in load-reduced dual in-line memory modules (LRDIMMs) at up to DDR3-1600 speeds at voltages of 1.5V and 1.35V. The MB3 features full source synchronous DRAM training algorithms, ultra-flexible pattern generation, error insertion/detection, and on-die scope capability via software.

LRDIMM targets applications such as cloud computing servers which require scalable memory architectures. LRDIMM technology delivers that scalability with a "pay as you go" approach to appropriately size a server's main memory pool as the user base evolves. Unlike RDIMMs, the performance of LRDIMMs does not significantly degrade as the number of DIMMs in a channel increases, maximizing the efficiency of a given set of CPU resources." said by IDT.

"LRDIMM is a critical technology to enhance server performance in virtualized environments such as Cloud Computing," said Mario Montana, vice president and general manager of the Enterprise Computing Division at IDT. "IDT is the industry leader in memory buffer technology dating back to FBDIMM, and that expertise and domain knowledge is applied to our MB3 products for DDR3. We have worked diligently with our customers, ecosystem partners and the JEDEC standards group to bring this new technology to fruition."

IDT MB301L manages all signals between the memory controller and SDRAM. By improving signal integrity both in the motherboard channel and on the LRDIMM, and effectively training the exchange of data to and from the DRAMs, the IDT MB301L allows higher densities of memory to be run at greater speeds and with fewer population restrictions than when using RDIMMs.
