Claim 12:
13. The method of claim 1, further comprising:
determining repair priorities of repair processing for the unrepaired FBs, and repairing the FBs according to the repair priorities,
wherein the repair priorities comprise:
a first repair priority, a new segmenting feature map group is generated after segmentation processing is performed on the segmenting feature map, and an RWL count of the segmenting feature map after FB repair processing is greater than the first preset numerical value;
a second repair priority, after repair processing is performed on the FB, the segmenting feature map is segmented, and a new segmenting feature map group is generated;
a third repair priority, after repair processing is performed on the FB in the basic repair bank, the RWL count corresponding to the basic repair bank is equal to 0;
a fourth repair priority, an FBL corresponding to a maximum number value in the first BL maximum FB, or an FBL corresponding to a maximum number value in the second BL maximum FB;
a fifth repair priority, a target fail WL, the target fail WL being a maximum fail WLs corresponding to the larger number value in two maximum fail WLs comprising FBLs;
a sixth repair priority, the FB corresponding to a maximum number value in the FBL;
a seventh repair priority, an RBL configured to repair FBLs and corresponding to a minimum number value in the segmenting feature map; and
an eighth repair priority, a first FB that is randomly determined.
