Abstract: A method for enhancing durability of a three-dimensional NAND flash memory. The method is based on a NAND flash memory having a three-dimensional structure, and comprises: for a device having performed multiple erase and programming operations, if a BER reaches a threshold set by a user, keeping the device in a final erased state, and performing annealing on the device. If a memory unit is kept in a random write state or in a highest G state after the device has performed an erase/programming operation, the restoration operation does not occur. The present invention performs high-temperature annealing on a memory in an erased state and compared with ordinary methods, an error rate is significantly reduced after a process of this method is completed. The invention enhances the durability of three-dimensional NAND flash memories by using a simple method, and repairs, by means of high-temperature annealing, data damage of three-dimensional NAND flash memories caused during PE cycles.
