Abstract

The present invention is related to methods and systems for refreshing non-volatile memories. A refresh token associated with a first wordline is located. A determination is made as to whether a first cell current for a first cell coupled to the first wordline is within a first range. At least partly in response to determining that the first cell current is within the first range, the first cell is refreshed.
