Abstract:
1. A method for operating non-volatile storage, comprising: performing a plurality of sense operations on at least one set of non-volatile storage elements which are programmed to a plurality of programming states, wherein the plurality of sense operations comprise sense operations which are performed when the set of non-volatile storage elements has a first number of program/erase cycles and sense operations which are performed when the set of non-volatile storage elements has a second number of program/erase cycles; providing a set of reliability metrics based on the plurality of sense operations; and storing the set of reliability metrics for an iterative probabilistic decoding process in determining a programming state of at least one non-volatile storage element based on at least one subsequent sense operation involving the at least one non-volatile storage element, wherein the non-volatile storage element is in the set of non-volatile storage elements.
