Abstract
A storage device includes a connection unit to which a first external device is to be connected, a first non-volatile memory in which content items are stored with associated content IDs, a first controller configured to access the content items stored in the first non-volatile memory, an antenna, a second non-volatile memory in which permission information is stored, and a second controller configured to update the permission information based on update information received from a second external device through the antenna. The update information is contained in radio waves transmitted by the second external device and the radio waves cause the antenna to generate power necessary to operate the second non-volatile memory and the second controller. In response to a read command from the first external device, the first controller performs a read of one of the content items based on the updated permission information.
