Abstract: Systems and methods for storing and/or communicating digital data associated with amplitudes and phases of a virtual periodic waveform having a designated period between components include, in one embodiment, circuitry that converts a first amplitude and a first phase to a first corresponding voltage or current and applies the first corresponding voltage or current to a first one of the plurality of components, such as conductors connecting integrated circuit chips or capacitors of a DRAM device, and converts the first amplitude and the first phase to (n?1) corresponding voltages or currents based on amplitudes of the periodic waveform phase shifted by about m*(360/n) relative to the first phase where m is indexed from one to (n?1) and applies each corresponding voltage or current to an associated component. Decoding is performed by comparing magnitudes of the component signals relative to one another rather that to a plurality of thresholds.

Abstract: Systems and methods for communicating digital data associated with amplitudes and phases of a virtual periodic waveform having a designated period between components connected by n conductors include, in one embodiment, circuitry that converts a first amplitude and a first phase to a first corresponding voltage or current and applies the first corresponding voltage or current to a first one of the plurality of conductors, and converts the first amplitude and the first phase to (n?1) corresponding voltages or currents based on amplitudes of the periodic waveform phase shifted by about m*(360/n) relative to the first phase where m is indexed from one to (n?1) and applies each corresponding voltage or current to an associated conductor of the plurality of conductors. The systems and methods are particularly suited for reducing the number of conductors to obtain a desired I/O data rate/throughput for integrated circuit chips and wired networks.
