Emerging next generation memories, NVRAMs, such as Phase-change RAM (PRAM), Ferroelectric RAM (FRAM), and Magnetic RAM (MRAM) are rapidly becoming promising candidates for large scale main memory because of their high density and low power consumption. Many researchers have attempted to construct a main memory with NVRAMs, in order to make up for the limits of NVRAMs. However, the authors find that the preexisting page caching algorithms, such as LRU, LIRS, and CLOCK-Pro, are often sub-optimal for NVRAMs due to its DRAM-oriented design including uniform access latency and unlimited endurance. Consequently, the algorithms cannot be directly adapted to the hybrid main memory architecture with PRAM.
