The cost of a semiconductor device is to be reduced. An electrical connection between a first semiconductor chip and a second semiconductor chip stacked on the first semiconductor chip is made through an inner lead portion of a lead disposed at a position around the first semiconductor chip and two bonding wires.

Semiconductor device having stacked semiconductor chips sealed with a resin seal member

A semiconductor device which has an internal circuit for performing a circuit operation corresponding to a signal inputted or outputted through an input/output interface circuit adapted to a serial bus. The semiconductor device has a non-volatile storage circuit for storing identification data. Internal identification data stored in the non-volatile storage circuit is compared with external identification data included in an input signal supplied through the serial bus by a comparator circuit. A control circuit is responsive to a match detecting signal generated by the comparator circuit to perform a circuit operation corresponding to an input signal subsequently supplied through the serial bus to change the internal identification data stored in the non-volatile storage circuit.
