A memory block having a plurality of parameter data including parameter data to be updated is read to a working area from a nonvolatile memory and, whether the plurality of parameter data is correct or not is checked on a basis of error detection data. When an error is detected, temporary updating data are generated in a working area by updating the parameter data to be updated to a specified parameter data and by updating data except the parameter data to be updated to an unspecified data that have no meaning, and then the temporary updating data are written into the nonvolatile memory.
