Abstract
A data input buffer includes a switching circuit; a reception circuit that includes a reception response unit and a reference response unit; and a code generating circuit. The data input buffer buffers a reception data signal to generate a buffered data signal, the reception data signal being an analog signal, and the buffered data signal being a digital signal, and a relative magnitude of a reference response conductance with respect to the reception response conductance is sequentially changed according to a sequential change of the calibration code, in the calibration mode.
