PROBLEM TO BE SOLVED: To provide a control device for preventing data from being stored in an ECC (Error Checking and Correction) memory while the error of data is not corrected. SOLUTION: This control device includes: an ECC memory 11 having a normal operation time area 12 to be accessed in a normal operation and an abnormal operation time area 13 to be accessed in the normal operation; a control task processing means 14 for performing control arithmetic processing by using a normal operation time area 12 of the ECC memory 11 in a normal operation; and a fixed cycle memory correction task processing means 15 for storing the whole area of the ECC memory 11 in a fixed cycle.
