Claim:
1. An on-die termination (ODT)/driving circuit comprising: a connection pad; a sub-circuit, wherein a first side of the sub-circuit is coupled to the connection pad; a first switch coupled to a second side of the sub-circuit, wherein the second side of the sub-circuit is opposite the first side of the sub-circuit, and the first switch is configured to selectively couple the second side of the sub-circuit to a supply voltage; a second switch coupled to the second side of the sub-circuit, wherein the second switch is configured to selectively couple the second side of the sub-circuit to a reference voltage; and a receiver coupled to a node located between the connection pad and the first side of the sub-circuit; wherein the receiver is configured to be deactivated when the ODT/driving circuit is in a driving mode, and the receiver is configured to be activated when the ODT/driving circuit is in an ODT mode, wherein the activated receiver is coupled to the supply voltage through the first switch when the second switch is opened or the activated receiver is coupled to the reference voltage through the second switch when the first switch is opened.
