Abstract
A data preserving method and a data accessing method for a non-volatile memory are provided. In the data preserving method, a data is checked according to an error correcting code (ECC) to obtain an error bit number of the data. When the error bit number is greater than a threshold, the data is moved from a first memory unit to a second memory unit and is corrected according to the ECC. Thereby, the data stability of the non-volatile memory is improved.
