Rambus Inc. and Kingston Technology have partnered to develop a threaded module prototype using DDR3 DRAM technology. Initial results exhibit 50 percent improvement in data throughput, and 20 percent reduction in power consumption, compared to conventional modules.

As demand grows for throughput-intensive computing in notebooks, desktops and servers, the performance requirements on DRAM memory subsystems rises dramatically. As a result, multicore computing requires more bandwidth and higher rates of random access from DRAM memory.

"As multicore computing becomes pervasive, DRAM memory subsystems will be severely challenged to deliver the data throughput required," said Craig Hampel, Rambus fellow. "Our innovative module threading technology employs parallelism to deliver the higher memory bandwidth needed for multicore systems while reducing overall power consumption."

"The collaboration of our experienced teams produced a memory solution that helps overcome a major challenge with multicore computing," said Ramon Co, VP of worldwide test engineering at Kingston.

Threaded memory module technology is implemented using industry-standard DDR3 devices and a conventional module infrastructure. It is capable of providing greater power efficiency for computing systems by partitioning modules into multiple independent channels that share a common command/address port. Threaded modules can support 64byte memory transfers at full bus utilization, resulting in efficiency gains of up to 50 percent when compared to current DDR3 memory modules. In addition, DRAMs in threaded modules are activated half as often as in conventional modules, resulting in a 20 percent reduction in overall module power.
