According to an embodiment, a semiconductor memory device includes a first pin, a first receiving circuit, and a first terminating circuit. The first pin receives a first signal and a second signal having a smaller amplitude than the first signal. The first receiving circuit is connected to the first pin and outputs, based on a comparison between the first signal and a first voltage, a third signal. The first receiving circuit also outputs, based on a comparison between the second signal and a second voltage, a fourth signal having a smaller amplitude than the third signal. The first terminating circuit is connected to the first pin. The first terminating circuit is disabled if the first pin receives the first signal, and enabled if the first pin receives the second signal.
