Abstract
Methods of programming nonvolatile memory devices include programming a plurality of nonvolatile multi-state memory cells in the non-volatile memory device with state-converted data derived from non-state-converted data. This state-converted data may be associated with a greater number of erased states relative to the non-state-converted data, when programmed into the plurality of nonvolatile memory cells. The methods also include generating a flag having a value that indicates which ones of the plurality of nonvolatile memory cells have been programmed with data that is swapped with data in other ones of the plurality of nonvolatile memory cells. This flag may also be programmed into the nonvolatile memory device. Operations may also be performed to read the state-converted data (and flag) from the plurality of nonvolatile memory cells and then decode the state-converted data into the non-state-converted data, based on the value of the flag.
