Non-Volatile Memory (NVM) is becoming an attractive candidate to be the swap area in embedded systems for its near-DRAM speed, low energy consumption, high density, and byte-addressability. Swapping data from DRAM out to NVM, however, can cause large performance/energy penalty and deplete the lifetime of NVM. Traditional swap mechanisms may need to be re-studied. Even through there are several swap mechanisms proposed for the hybrid DRAM-NVM systems, most of them have limited performance without considering the data access features of applications.
