The increasing gap between the speed of the processor and the time to access the data in the disk has historically been offset with deeper and larger memory hierarchies with multiple levels of SRAM, DRAM, and more recently, Flash layers for caching. However, recent trends that point to a potential slowdown of DRAM growth and the emergence of alternate resistive non-volatile memory technologies and properties of emerging data-centric workloads offer the opportunity to rethink future solutions. Specifically, in this paper, the authors examine an approach that leverages both the memory-like and disk-like attributes of emerging non-volatile memory technologies.
