Abstract
A semiconductor device includes an on-chip termination circuit, a reference voltage generator, and an input buffer. The on-chip termination circuit generates a variable resistance to an input signal based on at least one code signal. The reference voltage generator generates a reference voltage based on the code signal. The input buffer generates an internal signal based on the input signal from the on-chip terminal circuit and based on the reference voltage.
