  • Methods and systems for recovering data in a nonvolatile memory array
    Patent number: 7561465
    Abstract: One embodiment of the invention relates to a method for refreshing a nonvolatile memory array. In the method, a threshold voltage of a multi-bit memory cell is analyzed to determine if it has drifted outside of a number of allowable voltage windows, wherein each allowable voltage windows corresponds to a different multi-bit value. If the threshold voltage of the cell has drifted outside of the number of allowable voltage states, then the cell is recovered by adjusting at least one voltage boundary of at least one of the number of allowable voltage states.
    Type: Grant
