Abstract
A repair method and circuit for a memory is provided. The repair method includes the steps as follows: the memory receives a repair instruction sent from the outside, where the repair instruction carries a failed address, and the failed address is a memory cell address of a failed memory cell. A fuse array is broadcast and whether a currently broadcast fuse address is a target fuse address is sequentially determined, until at least one target fuse address is found, where the target fuse address is a fuse address mapped to a target redundant address, and the target redundant address is a redundant address capable of repairing the failed address. The failed address is written into the first unused target fuse address in the at least one target fuse address, to access the target redundant address when a request for accessing the failed address is received.
