Abstract
A memory device includes a memory area directly inaccessible from an electronic device; a secure control section that manages access to this memory area; and a device control section that communicates with the electronic device and transfers a request of the electronic device to the secure control section. The secure control section temporarily delegates, to a device control section, access rights to the memory area if there is write/read request of large capacity data from an authenticated electronic device, and the device control section to which this access rights have been delegated write/read data sent from the electronic device into/from the memory area by burst transfer.
