Abstract
A semiconductor device includes: a data clock signal generator circuit configured to output a plurality of data clock signals that have different phases and that are used to generate a plurality of internal data clock signals of a memory device; a data transmitter configured to generate a data signal based on a test pattern transitioned once, delay the data signal once transitioned according to a delay value, and output the data signal to the memory device; a data receiver configured to receive an output signal from the memory device that includes first sampling data, the first sampling data being obtained by sampling the data signal based on a first internal data clock signal from the plurality of internal data clock signals; and a training circuit configured to change the delay value and determine a final value of the delay value based on the first sampling data.
