A semiconductor device includes a multilevel receiver including a signal determiner receiving a plurality of multilevel signals and outputting a result of mutual comparison of the plurality of multilevel signals as an N-bit signal, where N is a natural number equal to or greater than 2. A decoder restores a valid signal among the N-bit signals from the signal determiner to an M-bit data signal, where M is a natural number less than N. A clock generator receives a reference clock signal, generates an input clock signal using the reference clock signal, inputs the input clock signal to the signal determiner, and determines a phase of the input clock signal based on an occurrence probability of an invalid signal not restored to the M-bit data signal among the N-bit signals.

A signal receiver includes a data sampler receiving a differential input signal having first and second input signals and determining bit values of the differential input signal based on first and second reference voltages, and a reference voltage generator performing a pre-tuning operation and a post-tuning operation to generate the reference voltages. The reference voltage generator performs the pre-tuning operation by generating first and second initial voltages and adjusting one of the initial voltages to generate third and fourth voltages. After the pre-tuning operation, the reference voltage generator performs the post-tuning operation by increasing or decreasing the third voltage to generate the first reference voltage and decreasing or increasing the fourth voltage to generate the second reference voltage based on a comparison result between the third voltage and the first input signal and a second comparison result between the fourth voltage and second input signal.
