A semiconductor package facilitates package connection due to different locations of input/output pads in each interlayer die depending on coding information in a multi-chip package. The semiconductor package includes many chips. Each of the chips includes: input/output pads configured to input and output data having a given bandwidth; a decoding pad configured to receive coding information; and a code control unit configured to decode the coding information and to enable an input/output pad positioned at a specific location among the input/output pads according to the decoding result.
