GR-FB block cleaning scheme in flash memory.


Abd.Rahiman, Amir Rizaan and Mansor, Noridayu and Abdul Halin, Alfian and Putra Sumari, and Kamarulhaili, Hailiza (2011) GR-FB block cleaning scheme in flash memory. In: International Conference on Advances in Information and Communication Technologies 2011, 1-2 Dec. 2011, Amsterdam, Netherland. .


Flash memory is a non-volatitle memory that offers several superior advantages as a data storage device in many electronic gadgets. However its two operational characteristics, namely 1) Out-place updating and 2) Cleaning process will affect its performance as an efficient storage sub-system if not managed wisely. This paper proposes a new block cleaning scheme, called Greedy and Frequency-based (GR-FB). The scheme combines the victim block selection procedure and the valid-data re-organizing procedure to improve the block cleaning process performance. The trace-driven simulations have shown the GR-FB scheme performs better than existing cleaning process schemes where the cleaning cost is reduced at least by 8% and the wear-leveling level for all blocks in the memory array are nearly equal.
