Abstract
A RFID device has a nonvolatile ferroelectric memory including a memory cell array area supplied only with a high voltage and a peripheral area supplied with a low voltage, thereby reducing power consumption. The RFID device includes an antenna adapted and configured to transceive a radio frequency signal from an external communication apparatus, an analog block adapted and configured to generate a power voltage in response to the radio frequency signal received from the antenna, a digital block adapted and configured to receive the power voltage from the analog block, transmit a response signal to the analog block and output a memory control signal, and a memory adapted and configured to generate a high voltage with the power voltage and access data in response to the memory control signal.
