主权项 1. A method of refreshing a nonvolatile memory having memory cells, the method comprising: identifying one or more of the memory cells that do not satisfy a data retention test; remapping the one or more identified memory cells from original memory addresses to spare memory addresses; refreshing the one or more identified memory cells; and remapping the one or more identified memory cells from the spare addresses back to the original addresses after the nonvolatile memory ceases to be at a temperature that is greater than a predetermined temperature.
