The Potential and Perils of Multi-Level Memory
Jagan Jayaraj, Arun F. Rodrigues, Simon David Hammond, Gwendolyn Voskuilen · 2015
The future of memory systems is Multi-Level Memory (MLM). In a MLM system the main memory is comprised of two or more types of memory instead of a conventional DDR-DRAM-only main memory. By combining different memory technologies, an MLM system can potentially offer more usable bandwidth and more capacity for a similar cost as a conventional memory system. However, substantial software and hardware design challenges must be overcome to make this potential real.
