An on die termination (ODT) circuit includes a signal input terminal; a grounding terminal; a first transistor including a control terminal and a first terminal which are electrically connected with the signal input terminal, and a second terminal electrically connected with the grounding terminal; and a second transistor including a control terminal electrically connected with the signal input terminal, a first terminal, and a second terminal electrically connected with the grounding terminal, and when voltage of the signal input terminal changes, the first transistor has a change trend of resistance opposite to that of the second transistor.
