Abstract
Disclosed herein are a method and apparatus for extending the lifetime of a non-volatile trapped-charge memory. A method includes setting limits of a memory sense window between an intrinsic threshold voltage of a non-volatile trapped-charge memory device and one of an end-of-life (EOL) value of a threshold voltage of a programmed state of the memory device and an EOL value of a threshold voltage of an erased state of the memory device. The data state of the memory device is then sensed.
