An RFID device includes an analog block configured to receive a radio frequency signal so as to output an operation command signal, a digital block configured to output an address, a temperature address, an operation control signal, and a temperature sensor activation signal in response to the operation command signal received from the analog block and to provide a corresponding response signal into the analog block. The device further includes a memory block configured to receive the address, the temperature address, and the operation control signal so as to generate an internal control signal for controlling the internal operation, and to read/write data in a cell array including a non-volatile ferroelectric capacitor in response to the internal control signal, and a temperature sensor processing unit configured to detect a temperature change state of an RFID tag in response to the temperature sensor activation signal.
