Electronic equipment including non-volatile memory means for storing control information

摘要

An electronic equipment includes a memory for storing information necessary for the execution of control programs and identification information which identify the control programs. A first check determines whether the identification information of the control program to be executed is equal to the identification information stored in the memory. A second check determines whether there is a vacant area in the memory when the decision by the first check indicates non-equality, and a control unit stores the information necessary for the control program to be executed in the memory together with the identification information thereof when the second check detects a vacant area.
