Abstract

A non-volatile storage system includes a mechanism to compensate for over programming during the programming process. That is, after the programming process starts for a set of data and target memory cells, and prior to the programming process completing for the set of data and the target memory cells, the system determines whether a first group of the memory cells has more than a threshold number of over programmed memory cells. If so, then the system adjusts programming of a second group of memory cells to reduce the number of programming errors.
