ABSTRACT:
A control apparatus for controlling a memory unit having an electrically erasable nonvolatile memory for storing information used in a process in an electrical equipment and a flash memory storing a processing program for executing the process in the electrical equipment. The control apparatus includes a loading program for loading information into the flash memory, which program is stored in the electrically erasable nonvolatile memory, a memory selecting circuit for selecting the flash memory when a first selecting information is supplied thereto, and selecting the electrically erasable nonvolatile memory when a second selecting information is supplied thereto, and a loading unit for supplying the second selecting information to the memory selecting circuit under a condition in which a program voltage is supplied from an external power supply thereto and for loading information in accordance with the loading program stored in the electrically erasable nonvolatile memory selected by the memory selecting circuit.
