Claim 9:
10. 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 second initial state, determining whether the bank feature map state is consistent with a fourth determination state in a second state set, the fourth determination state comprising that the available RBL count is greater than the first preset numerical value and the maximum WL FB count is equal to a second preset numerical value, or the available RBL count is equal to the second 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 fourth determination state, executing a second repair processing step in the fourth determination state,
wherein the second repair processing step in the fourth determination state comprises:
a repair step in the fourth determination state: acquiring a third maximum bit position corresponding to a third BL maximum FB in the segmenting feature map, and
triggering executing of the first initial repair processing step to repair the FB at the third maximum bit position; and
a determination step in the fourth determination state: determining whether the segmenting feature map subjected to the repair step in the fourth determination state satisfies a fourth determination condition, the fourth determination condition comprising that the target FB count is greater than 0, the available RBL count is greater than the first preset numerical value, a Fail Bit Line (FBL) count is greater than the first preset numerical value, the next remaining RWL count is greater than or equal to 0, and the maximum WL FB count is equal to the second preset numerical value, and
if the segmenting feature map subjected to the repair step in the fourth determination state satisfies the fourth determination condition, executing the second repair processing step in the fourth determination state.
