Rethinking the Memory Hierarchy Design with Nonvolatile Memories

Abstract: NVMs promise new persistent memory technology, which combines attractive attributes from both main memory (fast, load/store interface) and storage (data persistence). Unfortunately, supporting persistence in the memory can incur significant performance overheads; the well-studied memory hierarchy design is no longer well-suited to this new scenario. This talk will show our work on optimizing the performance of persistent memory systems with new memory control schemes and memory hierarchy design.
