    Abstract: A data receiving device of a memory device comprises a first pre-amplifier configured to receive previous data, a first reference voltage, and input data, and to output differential signals by comparing the input data with the first reference voltage in response to a clock, when the first pre-amplifier is selected in response to the previous data, a second pre-amplifier configured to receive inverted previous data, a second reference voltage, different from the first reference voltage, and the input data, and outputting a common signal in response to the clock, when the second pre-amplifier is unselected in response to the previous data; and an amplifier configured to receive the differential signals and the common signal, and to latch the input data by amplifying the differential signals.

    Abstract: A calibration circuit includes a first, second and third pull-up units each connected to a first power supply node, and first and second pull-down units each connected to a second power supply node. A first code generator is configured to generate a first code by comparing a voltage of a pad at which the first pull-up unit is connected to an external resistor with a reference voltage, and a second code generator is configured to generate a second code by comparing a voltage of a first intermediate node with the reference voltage and output the second code to the first and second pull-down units. A third code generator is configured to generate a third code by comparing a voltage of a second intermediate node between the second pull-down unit and the third pull-up unit with the reference voltage.
