MEMORY DEVICE AND RADIO COMMUNICATION CONTROL METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a memory device capable of controlling a radio communication function independently of control from a host device, and a radio communication control method thereof.SOLUTION: A memory device includes: a NAND flash memory; a control unit that controls the NAND flash memory; and a radio communication unit that is controlled by the control unit and has a radio communication function. The control unit has a first control mode in which when not receiving a control command for controlling the radio communication unit within a predetermined time period, the unit controls the radio communication unit on the basis of setting information; and a second control mode in which when receiving the control command for controlling the radio communication unit within the predetermined time period, the unit controls the radio communication unit on the basis of the control command.
