Claim:
1. A semiconductor package comprising: an external electrode; an interface chip including an external interface pad bonded to the external electrode, a plurality of internal interface pads, and an interface circuit coupled between the external interface pad and the plurality of internal interface pads; and a semiconductor chip including a signal pad that is selectively bonded to a selected internal interface pad of the plurality of internal interface pads; wherein the interface circuit is configured to activate a connection between the selected internal interface pad that is bonded to the signal pad and the external interface pad, and deactivate connections between unselected internal interface pads among the plurality of internal interface pads that are not bonded to the signal pad, and the external interface pad, and wherein the interface circuit comprises a fuse circuit configured to store connection information that represents which internal interface pad from among the plurality of internal interface pads is selected and bonded to the signal pad, a decoder configured to generate a path control signal by decoding the connection information read from the fuse circuit, and a switch configured to connect the external interface pad to the selected internal interface pad based on the path control signal.
