A set of non-volatile storage elements are erased to an erased threshold voltage distribution. A multi-pass programming process is performed that programs the set of non-volatile storage elements from the erased threshold voltage distribution to a set valid data threshold voltage distributions. Each programming pass has one or more starting threshold voltage distributions and programs non-volatile storage elements to at least two ending threshold voltage distributions.
