Abstract:
A flash memory controller includes a control unit, a buffer, an error correction code (ECC) module, and a configuring unit. The flash memory has a data area for storing the data content and a first spare area for storing a first ECC value corresponding to the data content. The ECC module utilizes the data content for generating a second ECC value and comparing the second ECC value with the first ECC value to determine whether the data content comprises a plurality of errors. The configuring unit computes the amount of the errors to determine whether the amount of the errors exceeds a predetermined threshold. If The configuring unit configures the data area and assigns a portion of the data area to be a second spare area. The first and the second spare area are associated with the ECC capability to allow the ECC module to correct the errors.

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.
