RADIO FREQUENCY IDENTIFICATION DEVICE HAVING NONVOLATILE FERROELECTRIC MEMORY

摘要

A RFID device having an analog block, a digital block, and a memory block having a nonvolatile ferroelectric memory is presented. The analog block is configured to receive a radio frequency signal so as to output an operating command signal. The digital block is configured to generate and output an address and an operation adjusting signal in response to the operating command signal. The digital block is also configured to output a response signal to the analog block and to generate a flag data corresponding to a data processing state and value. The memory block is configured to read and write a data in a nonvolatile ferroelectric capacitor in response to the operation adjusting signal. The memory block includes a memory unit configured to store the flag data so as to output the flag data to the digital block.
