Apparatuses and methods for a multi-level communication architectures are disclosed herein. An example apparatus may include an input/output (I/O) circuit comprising a driver circuit configured to convert a first bitstream directed to a first memory device and a second bitstream directed to a second memory device into a single multilevel signal. The driver circuit is further configured to drive the multilevel signal onto a signal line coupled to the first memory device and to the second memory device using a driver configured to drive more than two voltages.
