A semi-dual reference voltage data receiving apparatus includes a first input buffer, a second input buffer, and a phase detector wherein the first input buffer includes a first input receiving unit, a first sense amplifier, and a first current offset controlling unit. The first sense amplifier senses and amplifies the voltage difference between the voltage of a first terminal of a first input transistor and the voltage of a first terminal of a second input transistor. The first current offset controlling unit controls the offset of the current that flows through the second terminal of the second input transistor.
