Abstract:
Embodiments include methods, apparatuses, and instructions for encoding a codeword of data as codeword portions stored across multiple die in a non-volatile memory. Embodiments further include a decoder which may be configured to decode the portions of the codeword using hard decision reads. The decoder may then be configured to estimate the quality of each die, and apply a scaling factor to the decoded codeword portions such that confidence or reliability information can be determined for the codeword.
