Claim 8:
9. The method of claim 6, wherein said executing the second FB position determination step to determine the bit position of the second FB in each target repair region and performing second repair processing on the second FB according to the bit position of the second FB comprises:
if the bank feature map state is the first initial state, determining whether the bank feature map state is consistent with a third determination state in the first state set, the third determination state comprising that the available RBL count is greater than the first preset numerical value and the maximum WL FB count is greater than the first preset numerical value; and
if the bank feature map state is consistent with the third determination state, executing a second repair processing step in the third determination state,
wherein the second repair processing step in the third determination state comprises:
a repair step in the third determination state: acquiring the first maximum bit position corresponding to the first BL maximum FB and a second maximum bit position corresponding to a second BL maximum FB in the segmenting feature map respectively, and
if the maximum bit position and the second maximum bit position comprise a same position, triggering executing of the first initial repair processing step to repair an FB at the same position; and
a determination step in the third determination state: determining whether the segmenting feature map subjected to the repair step in the third determination state satisfies a third determination condition, the third determination condition comprising that the target FB count is greater than 0, the available RBL count is greater than the first preset numerical value, and the next remaining RWL count is greater than or equal to 0, and
if the segmenting feature map subjected to the repair step in the third determination state satisfies the third determination condition, executing the repair step in the third determination state.
