Flash memory has a variety of advantages such as the better performance compare to hard disk, shock resistance, small size, and so on. Therefore the use ratio of flash memory is being increased. But if the power-off failure is occurred, flash memory storage systems may loss mapping information. So in this paper, we propose power-off recovery scheme, called C-HYFLUR. We have applied C-HYFLUR to page mapping FTL and implemented on a platform board, and compared with the existing recovery schemes through several evaluations. Compare to existing recovery schemes, the overhead of C-HYFLUR is very low.
