Abstract
The semiconductor device includes a flag signal generator, a reference voltage generator and a first buffer. The flag signal generator generates a flag signal in response to an internal command and an information code. The reference voltage generator receives a set code in response to the flag signal, and generates a reference voltage having a voltage level regulated according to the set code. The first buffer buffers the external signal in response to the reference voltage to generate an internal signal, and generates a calibration code in response to the flag signal.
