Abstract
Systems and methods are described for transmitting data over physical channels to provide a high speed, low latency interface such as between a memory controller and memory devices with significantly reduced or eliminated Simultaneous Switching Output noise. Controller-side and memory-side embodiments of such channel interfaces are disclosed which do not require additional pin count or data transfer cycles, have low power utilization, and introduce minimal additional latency. In some embodiments of the invention, three or more voltage levels are used for signaling.
