    Abstract: Multi-chip package includes first through Nth semiconductor chips, each of which includes an input/output pad, an input/output driver coupled to the input/output pad, and an internal circuit. Each of the first through Nth semiconductor chips includes an internal pad for coupling the internal input/output driver and the internal circuit. The internal pads of the first through Nth semiconductor chips are coupled to each other such as via a common pad installed at a substrate. The input/output pad of the first semiconductor chip directly receives an input/output signal transmitted via a corresponding pin of the multi-chip package. The second through Nth semiconductor chips indirectly receive the input/output signal via the internal pads coupled to each other. The multi-chip package can improve signal compatibility by maintaining a parasitic load of a pin to at least the level of a single chip, when a signal is transmitted to the pin at high speed. Also, when a signal that is not necessarily transmitted at high speed is applied to a pin, semiconductor chips can be packaged according to the preexisting methods.
