Abstract
A method for correcting bit defects in an STT-MRAM memory is disclosed. The method includes reading a codeword in the STT-MRAM memory, wherein the STT-MRAM memory includes a plurality of codewords, wherein each codeword includes a plurality of redundant bits. Further, the method includes mapping defective bits in the codeword to redundant bits of the plurality of redundant bits based on a mapping scheme, wherein the mapping scheme is operable to determine a manner in which the defective bits in the codeword are to be mapped to the redundant bits. Finally, the method includes replacing the defective bits in the codeword with corresponding mapped redundant bits.
