Claim 14:
15. The method of claim 14, further comprising:
performing a third sensing operation on the plurality of non-volatile memory cells to distinguish between a third data state of the non-volatile memory cell and a fourth data state of the non-volatile memory cell; and
subsequent to performing the third sensing operation, performing a fourth sensing operation on the memory cells to determine a reliability of the third sensing operation for memory cells determined to be in the fourth data state, but not for memory cells determined to be in the third data state, by the third sensing operation, wherein
performing the error correction code operation further uses results of the third sensing operation and the reliability of the third sensing operation for memory cells determined to be in the fourth data state, but not for memory cells determined to be in the third data state, to determine data content stored in the plurality of non-volatile memory cells.
