ABSTRACT:
A storage device for refreshing pages of a flash memory comprises a flash memory, an ECC detector and a controller. The flash memory has a plurality of pages, and each page comprises a data area for storing data and a spare area for storing error correction code (ECC) corresponding to the data. The ECC detector is used to get the number of error bits of each page. The controller coupled to the ECC detector is used for storing data and ECC in a first page to a second page when a number of used bytes of the ECC stored in a spare area of the first page exceeds a first predetermined value. A number of used bytes of the ECC stored in a spare area of the second page is less than the first predetermined value. The second page is a blank page.
