ABSTRACT:
A method for operating a memory includes applying at least one pulse to a group of analog memory cells, so as to cause the memory cells in the group to assume respective storage values. After applying the pulse, the respective storage values are read from the memory cells in the group. One or more statistical properties of the read storage values are computed. A wear level of the group of the memory cells is estimated responsively to the statistical properties.
