A semiconductor chip includes a plurality of pads; input/output circuits
connected with the plurality of pads, respectively; a product data
storage section configured to store a product data; and a setting section
configured to set to an active state, each of the input circuits which is
connected to one of the plurality of pads used for input to an internal
circuit, and each of the output circuits which is connected to one of the
plurality of pads used for output from the internal circuit, and set
remaining input/output circuits to an inactive state, based on the
product data.
