Abstract
A semiconductor chip for an RFID tag is described. The semiconductor chip including wireless transceiver and processing block circuitry to receive and put into effect a wirelessly received instruction encoded in a TUNE command. The instruction commanding the semiconductor chip to perform at least one specific act. The semiconductor chip having circuitry to perform the at least one specific act. The circuitry being coupled to the processing block. The circuitry and its corresponding specific act identified by at least one of the following: enablement circuitry to turn a sub-circuit within the semiconductor chip on; disablement circuitry to turn a sub-circuit within the semiconductor chip off; current bias circuitry to alter a bias current within a sub-circuit of the semiconductor chip; voltage bias circuitry to alter a bias voltage within a sub-circuit of the semiconductor chip; threshold adjustment circuitry to adjust a threshold within a sub-circuit of the semiconductor chip.
