Abstract
Methods include receiving data and an ECC code read from a memory array, generating an ECC code from the received data, and determining whether the received data is corrupted by evaluating the generated ECC code against the ECC code read from the memory array. If the received data is determined to be corrupted, a correction algorithm and a recorded likely state of a known bad/questionable bit of the received data may be used to correct error in the received data. Alternatively, if the received data is determined to be corrupted, the correction algorithm and a recorded location of a known bad/questionable bit of the received data may be used to correct error in the received data.
