Abstract: A semiconductor device that is difficult to reverse engineer. The semiconductor device includes a reconfigurable circuit having a circuit configuration that is switchable in accordance with circuit operation setting data. A non-volatile memory stores the circuit operation setting data. A register receives the circuit operation setting data from the non-volatile memory and provides the circuit operation setting data to the reconfigurable circuit when the semiconductor device is activated. Since the circuit configuration of the reconfigurable circuit is determined by the circuit operation setting data, the operation of the reconfigurable circuit cannot be analyzed when a peeling analysis is conducted on the semiconductor device.

The main device includes an authentication device and an ID check device, which is incorporated in an exclusive authentication chip. The authentication device is arranged separately from the exclusive authentication chip. In response to an authentication request signal from the authentication device, the ID check device generates a first identification signal for the main device and compares it with a second identification signal of the external device. The ID check device then provides the authentication device with an authentication result signal that is in accordance with the comparison result. The authentication device only determines whether the external device is appropriate based on the authentication result signal.
