Adaptive Block level management for hybrid main memory

This paper proposes a PCM hybrid main memory management scheme called APABL (Adaptive PRAM aware Block-based LRU). Proposed scheme takes DRAM as the first memory and PCM as the spare memory. Only data evicted from DRAM is to be written into PCM. Our scheme can reduce both the access times to PCM and SSD without performance loss. Thus, it can also benefit the mobile computer.
