Patent ID: 8637998

Claim:
A semiconductor chip comprising: at least one first electrode pad provided in the semiconductor chip; a second electrode pad capable of outputting a signal identical to a signal outputted from the first electrode pad, the second electrode pad being at least one electrode pad provided in the semiconductor chip; an internal circuit for outputting a signal to at least either of the first electrode pad, and the second electrode pad: and a selector circuit for receiving a signal outputted from the internal circuit and outputting the signal to either of the first electrode pad, and the second electrode pad, wherein either of the first electrode pad and the second electrode pad, closer in distance to one other electrode pad of one other semiconductor chip where the signal is supplied, is coupled to the one other electrode pad of the one other semiconductor chip, wherein the selector circuit includes: a first AND circuit having an output terminal coupled to the first electrode pad, one input terminal for receiving the signal outputted from the internal circuit, the other input terminal for receiving a signal outputted from a setting circuit: and a second AND circuit having an output terminal coupled to the second electrode pad, one input terminal for receiving a signal identical to the signal outputted from the internal circuit to be supplied to the one input terminal of the first AND circuit, the other input terminal for receiving a second signal outputted from the setting circuit, and wherein the selector circuit varies respective signal levels of the first signal, and the second signal, outputted from the setting circuit, thereby switching the electrode pad to be coupled to the one other semiconductor chip.
