Patent ID: 7953368

Claim:
A first radio frequency integrated circuit chip, comprising: a first circuit unit including a non-volatile memory reading from, and writing a first data into, the non-volatile memory; a second circuit unit including a first volatile memory reading from, and writing a second data into, the first volatile memory; the second data held in the first volatile memory holding execution conditions and reading first data from and writing the second data to, the non-volatile memory; a first power supply with a first receiver receiving a first radio wave, and supplying power as a first electrical signal to the first circuit unit; and a second power supply with a second receiver receiving a second radio wave whose frequency is different from that of the first radio wave, and supplying power as a second electrical signal to the second circuit unit, wherein the first electrical signal which supplies power to the first circuit unit and the second electrical signal which supplies power to the second circuit unit contain information transmitted from a reader and a writer; an integrated circuit module performing processing and storage of the first data and the second data according to information contained in the first electrical signal supplied as power and according to information contained in the second electrical signal supplied as power; wherein the first circuit unit reads predetermined data to be maintained while the first volatile memory of the second circuit unit receives power supplied from the second power supply and the second power supply receives the second radio wave, by receiving the power supplied from the first power supply; wherein the processing and storage of the first data within the first circuit unit including the first volatile memory changes based on whether the second receiver is currently receiving the second radio wave; wherein the first radio frequency integrated circuit chip uses variable radio frequency communication levels depending on a use of the first circuit unit and the second circuit unit, wherein the first radio frequency integrated circuit chip is configured depending on a purpose, and depending on a usage of the first radio frequency integrated circuit chip, wherein the first volatile memory of the second circuit unit is only accessible during simultaneous operation of the first power supply and the second power supply, and wherein the reading and writing of the first radio frequency integrated circuit chip is controlled by a second radio frequency integrated circuit chip.
