System and method for redundancy implementation in a semiconductor device

摘要

A system and method for redundancy implementation in an integrated semiconductor device having at least one memory instance that includes a prime memory array and a redundant portion. A fuse box register is provided outside the memory macro cell associated with the memory instance. The fuse box register is operable to store location information pertaining to a faulty portion in the prime memory array. A redundancy scan storage element in the memory instance is operable to receive the location information from the fuse box register, which location information is used for replacing at least a part of the faulty portion in the prime memory array with at least a part of the redundant portion.
