1. A method of performing a data receiver offset calibration of a memory device, the method comprising:
storing a first parameter code in a mode register, the first parameter code being used to set a default data receiver offset calibration for the data receiver offset calibration;
storing a second parameter code in the mode register, the second parameter code being used to set an optional data receiver offset calibration for the data receiver offset calibration;
training the default data receiver offset calibration based on the first parameter code for the data receiver offset calibration; and
training the optional data receiver offset calibration based on the second parameter code for the data receiver offset calibration.
