Abstract: Apparatuses and methods for adding offset delays to signal lines of multi-level communication architectures are disclosed herein. An example method may include comparing a current channel state of a channel of a multi-level communication bus with a next channel state of the channel. The example method may further include, based on the comparison, applying an offset delay to a control signal configured to control transition of a signal line of the channel from a value associated with the current channel state to a value associated with the next channel state. The example method may further include after application of the offset delay, driving the signal line to the value associated with the next channel state responsive to the control signal.

Abstract: Apparatuses and methods for driving input data signals onto signal lines as output data signals are disclosed. An example apparatus includes a detection circuit, a driver adjust circuit, and a data driver. The detection circuit is configured to detect a characteristic(s) of a group of input data signals to be driven onto adjacent signal lines. A characteristic could be, for example, a particular combination of logic levels and/or transitions for the group of input data signals. The driver adjust circuit is configured to provide a driver adjustment signal based at least in part on a detection signal, that is provided by the detection circuit. A data driver is configured to drive a respective one of the group of input data signals as a respective one of the output data signals, wherein the data driver is adjusted based at least in part on the driver adjustment signal.
