Patent ID: 8019931

Claim:
A method for operating a nonvolatile memory, wherein the nonvolatile memory is configured so that an erased data pattern is read out when reading out a memory area that has not been written in, the method comprising: setting a memory area for storing operating variable data that are to be written, the memory area being ascertained by an address counter; 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 consecutively in the determined memory area if the operating variable data that are to be written are different from the erased data pattern; preventing the writing of the operating variable data in the determined memory area if the operating variable data that are to be written correspond to the erased data pattern; and incrementing the address counter after one of the writing or the preventing of the writing of operating variable data.
