Block Utilization-Aware Buffer Replacement Scheme for Mobile NAND Flash Storage
Dong Hyun Kang, Changwoo Min, Young Ik Eom · IEICE Transactions on Information and Systems · 2014
NAND flash storage devices, such as eMMCs and microSD cards, are now widely used in mobile devices. In this paper, we propose a novel buffer replacement scheme for mobile NAND flash storages. It efficiently improves write performance by evicting pages flash-friendly and maintains high cache hit ratios by managing pages in order of recency. Our experimental results show that the proposed scheme outperforms the best performing scheme in the recent literature, Sp.Clock, by 48%.
