An electronic device includes a first non-volatile memory for storing a control program for controlling an operation of the electronic device, and a second non-volatile memory for storing at least one modifying program for modifying the control program. The second non-volatile memory also stores modification information related to a modification of the control program. At least one predetermined portion of the control program can call a software modification management routine. The modification information is then read and the electronic device determines whether a modifying program to be executed is present in accordance with the modification information and address information, which indicates a current operating position of the control program, in response to the calling of the software modification management routine. The control program and the modifying program are then executed if the electronic device determines that the modifying program is present.
