1. An electronic control apparatus comprising:
a memory which stores data; a processor which executes control processing by using data stored in the memory; an error detection unit which detects a data error in data stored in the memory; an error correction unit which corrects the data error; and a data retention unit which retains data stored in the memory into a different storage area on the memory, wherein when the error detection unit detects the data error, the data retention unit retains data obtained as a result of correction of the data error conducted by the error correction unit into a second storage area different from a first storage area on the memory where the data error is detected, and after the data retention unit retains data into the second storage area, the processor uses the data on the second storage area for the control processing, and uses data on the first storage area as well for the control processing continuously.
