PROBLEM TO BE SOLVED: To provide a data writing control device which is capable of preventing erroneous data from being written by preventing the supply of an electric power to a storage part from being stopped during a data storage operation and to provide a data writing control method.SOLUTION: A data writing control device 1 comprises: an EEPROM 7 repeatedly performing the data storage operation being an operation for storing data for each predetermined information amount; a CPU 6 controlling the data storage operation by the EEPROM 7; a battery 2 supplying the electric power for performing the data storage operation to the EEPROM 7; and a capacitor 5 supplying the electric power for performing at least one data storage operation to the EEPROM 7, when the supply of the electric power from the battery 2 is interrupted. When the supply of the electric power from the battery 2 is interrupted, the CPU 6 inhibits the data storage operation which cannot be completed before the supply of the electric power to the EEPROM 7 from the capacitor 5 is stopped. |
