  • Patent number: 8223554
    Abstract: Each of the programming processes operate to program at least a subset of the non-volatile storage elements to a respective set of target conditions using program pulses. At least a subset of the programming processes include identifying a program pulse associated with achieving a particular result for a respective programming process and performing one or more sensing operations at one or more alternative results for the non-volatile storage elements. Subsequent programming process are adjusted based on a first alternative result and the identification of the program pulse if the one or more sensing operations determined that greater than a predetermined number of non-volatile storage elements achieved the first alternative result. Subsequent programming process are adjusted based on the identification of the program pulse if the one or more sensing operations determined that less than a required number of non-volatile storage elements achieved any of the alternative results.
