Abstract :
In order to achieve balanced flash memory writing in solid-state disks and extend their service life, dynamic mapping of logic sectors and actual physical sectors is established between the host device and the flash memory; A circular erasing algorithm is used to clean up dirty sectors produced in the sectors dynamic mapping process, and release invalid storage spaces effectively. The result of FPGA based test shows that the researched circular erasing algorithm is efficient.
