Memory modules using Intel’s 3D XPoint technology are on their way, and researchers in North Carolina have already figured out how to make them better. New submitter mnemotronic writes: At the 45th ICSA (International Symposium on Computer Architecture), a group of researchers from North Carolina State University led by Prof. Yan Solihin proposed a method called lazy consistency to speedup write operations to 3d XPoint memory. XPoint, developed by Intel and Micron, is non-volatile, cheaper and denser than DRAM but requires more power and writing takes longer. The method proposed reduces write overhead times from 9% to 1% by incorporating a checksum to the cache memory system. The researchers were not able to verify their approach on actual XPoint memory, as those products only recently started sampling. They tested using simulations and DRAM and plan to verify when Intel’s modules become more widely available.
