Abstract
Memory reliability is improved by using redundancy to repair errors detected by ECC. In one embodiment, redundancy repairs errors which cannot be corrected by ECC. The redundancy can employ the use of electronic fuses, enabling repairs after an IC containing the memory is packaged. Redundancy can also be performed prior to packaging of the IC.
