As per socket compute density increases, the amount of directly accessible, low-latency memory bandwidth and capacity to adequately feed data to the multiple cores needs to scale accordingly. Scaling memory bandwidth by increasing raw DRAM component bandwidth or by increasing the number of memory channels has challenges and is reaching limits. JEDEC has unveiled the development of a new DIMM technology called Multiplexed Rank Dual Inline Memory Modules (MRDIMM) to address the bandwidth challenge.
