摘要： A radio frequency identification (RFID) tag with embedded memory testing scheme and the method of testing the same is disclosed, in which the RFID tag is comprised of an analog block, a digital block and a memory block. Operationally, as the analog block receives and demodulates a memory self-test signal issued from a reader, the memory block is driven to issue a non-digital memory state signal to be received by the analog block where it is being converted into a digital memory state signal, and then the digital memory state signal is being transmitted to the digital block for enabling the same to make an evaluation to determine whether the received digital memory state signal fall within the range representing the memory is in good condition, and thereafter, the evaluation is send to the reader by the RFID tag so as to enable the reader to select a posterior process to be perform accordingly.
