access icon free Swap time-aware garbage collection policy for NAND flash-based swap system

A swap time-aware garbage collection (STGC) policy for the NAND flash-based swap system is proposed, which focuses on reducing the cleaning cost and improving the degree of wear-levelling. STGC calculates the cleaning index value of each block to select a victim block and the normalised value of the elapsed swap time of each valid page within the victim blocks to identify the hot valid page and cold valid page. Trace-driven simulations with a synthetic trace show that the STGC outperforms the existing garbage collection policies.
