    Abstract: An offset calibration training method for adjusting a data receiver offset and a memory device therefor are provided. A method of performing a data receiver offset calibration includes storing a first parameter code, which is used to set a default data receiver offset calibration for the data receiver offset calibration, in a mode register, storing a second parameter code, which is used to set an optional data receiver offset calibration for the data receiver offset calibration, in the mode register, 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.

    Abstract: A receiver for cancelling common mode offset and crosstalk that amplifies a voltage difference between an input signal and a reference voltage to generate first and second output signals and an internal signal, that generates the same third and fourth output signals as the first and second output signals, generates average voltage levels of the third and fourth output signals by using first and second switching elements and low pass filters to output the average voltage levels as first and second feedback signals, and cancels a common mode offset between the first output signal and the second output signal based on a voltage difference between the first feedback signal and the second feedback signal, and that generates a control signal to cancel crosstalk of the internal signal by turning on/off the first and second switching elements connected to the low pass filters.
