  • Data protection method for memory
    Patent number: 8230302
    Abstract: A data protection method is provided. The data protection method is adapted for a plurality of pages of a plurality of blocks in a memory. The data protection method records bit error weight values and erasing times of the blocks during routine operations of the memory. Therefore, when the system is in an idle status, the data of those blocks having higher bit error weight values can be recovered. Further, the data protection method moves data of those blocks having less erasing times to other blocks, so as to release the blocks having less erasing times from the data area for use. Then, the data protection method utilizes all blocks of the non-volatile memory in an average manner, so as to effectively protect the data saved in the memory and average the erasing operations.
