Optimal page allocation approach on the hybrid DRAM/PCRAM memory architecture

Non-volatile memory has the advantages of non-volatility, circuit density and ignorable leakage power. However, it suffers from the bad write latency and poor write power consumption. In this paper, we propose a page allocation approach on the hybrid DRAM/PCRAM memory structure. By dividing a task into page segments, we can further taking the advantages of good leakage consumption of PCRAM and short write latency of DRAM. Experimental results show that our page-based approach performs better than the task-based approach in terms of both latency and power consumption.
