Abstract
A method is for operating a memory having a group of non-volatile memory cells. A first programming pulse is applied to a subset of the group of non-volatile memory cells. The subset needs additional programming. A portion of the subset still needing additional programming is identified. A ratio of the number of memory cells in the subset and the number of memory cells in the portion is determined. A size of a second programming pulse based on the ratio is selected. The second programming pulse is applied to the portion.
