Classification: CPC G | IPC G

Claim 12:
13. The data accessing method according to claim 10, further comprising:
setting a first threshold value, wherein the first threshold value is less than a maximum number of correctable bits of an error correction code;
checking whether the normal data has at least one error bit, and calculating a number of error bits in the normal data;
comparing the number of the error bits in the normal data with the first threshold value;
if the number of the error bits is greater than the first threshold value, reading the weight data from the plurality of first bits of the multi-level cells and reading the normal data from the plurality of second bits and the plurality of third bits of the multi-level cells;
correcting the at least one error bit of the normal data by the error correction code and updating the weight data; and
writing the updated weight data to the plurality of first bits of the multi-level cells and writing the corrected normal data to the plurality of second bits and the plurality of third bits of the multi-level cells.
