Threaded memory module deal
Rambus and Kingston Technology are collaborating on the development of a threaded module prototype using DDR3 DRAM technology. According to the companies, initial results show data throughput can be boosed by up to 50%, with a 20% reduction in power consumption.
"As multicore computing becomes pervasive, dram subsystems will be severely challenged to deliver the data throughput required," said Craig Hampel, Rambus Fellow. "Our module threading technology employs parallelism to deliver the higher memory bandwidth needed for multicore systems, while reducing overall power consumption."
Threaded memory module technology, which uses standard DDR3 drams and conventional modules, supports 64byte memory transfers at full bus utilisation.
As demand grows for throughput-intensive computing in notebooks, desktops and servers, the performance requirements on DRAM memory subsystems rises dramatically. As a result, multi-core computing requires more bandwidth and higher rates of random access from DRAM memory.
"As multi-core 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 multi-core systems while reducing overall power consumption."
"Kingston is at the forefront of memory technology working closely with innovators like Rambus to develop advanced solutions," said Dr. Ramon Co, vice president of Worldwide Test Engineering at Kingston Technology. "The collaboration of our experienced teams produced a memory solution that helps overcome a major challenge with multi-core computing."
Threaded memory module technology is implemented utilizing 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 64-byte 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.
