Summary:PROBLEM TO BE SOLVED: To provide a missing data recovery device that restores missing data in a small circuit scale. SOLUTION: When a missing detection circuit part 35 inputs an error signal into a control logic circuit part 31, the control logic circuit part 31 wakes up. The control logic circuit part 31 then reads out memory data stored in an external memory 2. The control logic circuit part 31 next generates error detecting data by a predetermined arithmetic expression using the read memory data, and stores the generated error detecting data and the memory data read from the external memory 2 in a data holding register 34. The memory data are stored in the data holding register 34 to prevent the error signal from being input from the missing detection circuit part 35, so that the control logic circuit part 31 returns to a sleep state.
