Abstract
A semiconductor memory device and a semiconductor memory system. The semiconductor memory device includes channels configured to transmit signals from a transmitter to a receiver, and a crosstalk compensator. The crosstalk compensator may be connected between the channels to compensate for crosstalk. The crosstalk compensator may comprise a capacitor connected in parallel between the channels, and a switching unit connected between the capacitor and one of the channels. The switching unit may control connections or disconnections between the capacitor and the channel. Therefore, the semiconductor memory device and the semiconductor memory system compensate for crosstalk occurring between transmitted signals that are out of phase with each other.
