A method for operating a nonvolatile memory, wherein the nonvolatile memory is configured to read out an erased data pattern when reading out a memory area that has not been written in, and performing the operations or tasks of setting a memory area for storing operating variable data that are to be written, providing operating variable data to be written in the nonvolatile memory, checking whether the operating variable data to be written correspond to the erased data pattern of the memory area set, writing the operating variable data in the determined memory area if the operating variable data that are to be written are different from the erased data pattern, and if the operating variable data that are to be written correspond to the erased data pattern, preventing writing the operating variable data in the determined memory area.
