Abstract
A method and system are provided for error correction in a memory. Error correction code (ECC) for data stored in a portion of the memory is enabled. A location and number of errors for the portion of the memory is then stored. It is determined if the number of errors exceeds a predetermined number of errors. If the number of errors exceeds the predetermined number, then the data stored in the portion of the memory is refreshed. If refreshing does not correct the errors, then a different ECC may be used.
