Preprogrammed data recovery

Abstract:

Techniques for recovering preprogrammed data from non-volatile memory are provided that include majority voting and/or use of one or more levels of ECC correction. Embodiments include storage of multiple copies of the data where ECC correction is performed before and after majority voting with respect to the multiple copies. Multiple levels of ECC correction can also be performed where one level of ECC is performed at the local level (e.g. on-chip), whereas another level of ECC correction is performed at a system level.
