A semiconductor device includes a first wiring board, a second semiconductor chip, and a second seal. The calibration circuit includes an RF signal path configured to receive an RF signal corresponding to an output of the mixer, selectively receive a test signal injected into the RF signal path, and provide feedback to the mixer according to the RF signal andor the test signal. The rate of energy transfer may be equal to the energy drain caused by self-discharge and automated self-testing. The decrypted sensitive data is stored in a non-volatile memory such that the decrypted sensitive data are distributed in a plurality of memory segments of the non-volatile memory where a relationship of the memory segments is stored as relationship data independently of the stored decrypted sensitive data. Polynucleotides that encode such polypeptides and methods of regulating gene expression with such polypeptides and polynucleotides are also provided. The first computing element, the second computing element, and the reconfigurable interconnect operable to perform discrete functions suitable for processing of the communication signal.
