    摘要: In a control apparatus, a write control unit controls operation of writing data to a non-volatile storage unit. The write control unit is configurable with given control data. A control data storage unit stores first control data for the write control unit. An input reception unit receives second control data for the write control unit. A configuration unit configures the write control unit with the first control data stored in the control data storage unit when the first control data has a newer version number than that of the second control data received by the input reception unit, and with the second control data when the second control data has a newer version number than that of the first control data.
