Abstract: A memory controller includes a first receiver configured to compare a read reference voltage with a piece of data received through a first data line and output a first piece of data; a first duty adjuster configured to adjust a duty of the first piece of data; a second receiver configured to compare the read reference voltage with a piece of data received through a second data line and output a second piece of data; a second duty adjuster configured to adjust a duty of the second piece of data; and a training circuit configured to perform a training operation on pieces of data received through a plurality of data lines, to obtain a target read reference voltage for each piece of data and correct a duty of each piece of data based on a level of the target read reference voltage for each piece of data.

Abstract: A method of training a physical interface between a first device and a second device includes performing a first training of the physical interface by communicating with the second device by using a first candidate group of lanes from among a plurality of lanes; performing a second training of the physical interface by communicating with the second device by using a second candidate group of lanes from among the plurality of lanes, the second candidate group being different from the first candidate group; determining a lane group based on a result of the first training and a result of the second training; and setting the second device so that the determined lane group is used for the physical interface.
