Patent number: 7079043Abstract: A radio frequency identification device comprises an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.Type: GrantFiled: July 24, 2003Date of Patent: July 18, 2006Assignee: Micron Technology, Inc.Inventors: James E. O'Toole, John R. Tuttle, Mark E. Tuttle, Tyler E. Lowrey, Kevin M. Devereaux, George E. Pax, Brian P. Higgins, Shu-Sun Yu, David K. Ovard, Robert R. Rotzoll
