Abstract
A flash memory stores a boot program of a host system and its backup program. A memory controller determines whether or not the boot program is stored properly in the flash memory when the host system is to be activated. The memory controller reads out the boot program in a case where the boot program is stored properly, and reads out the backup program in a case where the boot program is not stored properly. Then, the memory controller supplies the read-out boot program or backup program to the host system. This makes it possible to avoid a situation that the host system cannot be activated due to the boot program not being able to be executed.
