After power activation, a transferer 14 detects a bootstrap program 111 having a first error check code 114 assigned thereto and being stored in a first storage device 11 , subjects the bootstrap program 111 to an error detection/correction process, and transfers the bootstrap program 111 to the second storage device 12 . If the transfer is properly completed, by executing the bootstrap program 111 on the second storage device 12 , the CPU 10 performs an error detection/correction process for a main program 112 having a second error check code 115 assigned thereto, and transfers the main program 112 to a third storage device 13 , after which the CPU's control branches out to the main program 112 on the third storage device 13 . As a result, system boot can be performed without employing a NOR type flash memory.
