Patented HyperCloud Technology Enables 1333 MT/s Memory Speeds on Future Intel Xeon E5 Family Based Two-Processor Servers While LRDIMM Only Enables 1066 MT/s

Netlist has announced results of side-by-side testing of its HyperCloud modules versus LRDIMM (load reduced dual inline memory module). The test results confirmed that HyperCloud is able to achieve 1333 MT/s (mega transfers per second) memory speeds while LRDIMM is only able to achieve 1066 MT/s.

The memory speed benefit is an important enabling factor for increased application performance for the many enterprises that engage in memory intensive supercomputing simulations, securities transactions and analytics for memory databases. This speed advantage will also be a key contributing factor in the decisions by major OEM server manufacturers to adopt HyperCloud for future generation of servers.

The testing was performed on identical systems at 3 DIMMs per channel (DPC) populated on future Intel Xeon E5 family based two-processor servers. HyperCloud is the patented high-performance virtual dual rank (2vR) RDIMM which overcomes traditional memory bottlenecks that limit server memory capacity and bandwidth.

"The fundamental difference between HyperCloud and LRDIMM is that HyperCloud is based on a distributed buffer architecture that reduces long data path delays by utilizing multiple small buffers located along the bottom (connector) edge of the module reducing the lengths of data signal paths between the data buffer and DRAMs," stated Dr. Hyun Lee, Chief Technology Officer, Netlist. "The LRDIMM, in contrast, uses a single buffer architecture that has longer data signal trace lengths between the DRAM and connector because all the data signals have to pass through a single buffer (register) and back out to DRAM."
