Future challenges for DDR4 and beyond

Rambus Blog, Aug. 25, 2015 – 

Ely Tsern, VP and chief technologist for the Rambus Memory and Interfaces division, has identified five key trends driving future server memory. These include Big Data, additional cores per CPU, a DRAM scaling slowdown, the emergence of storage class memory and the expectation that DDR4 will ultimately reach its speed limit.

"Rambus is working with customers and the industry to determine the most cost-effective ways to address these trends," he confirmed during a recent presentation at IDF 2015.

"The good news? DDR4 should be capable of scaling to 3.2 - 3.7 Gbps. Simply put, this means DDR4 has ~50% more headroom from systems shipping today."
