ABSTRACT:
Systems, methods, and devices are disclosed, such as an integrated semiconductor device that may include a data location coupled to an electrical conductor, a delta-sigma modulator coupled to the electrical conductor, a counter coupled to an output of the delta-sigma modulator, and an interfuser coupled to an output of the counter. In some embodiments, the interfuser is configured to receive two or more counts from the counter and read data conveyed by the data location based on the two or more counts.
