A semiconductor device with a packaging circuit portion connected to a semiconductor chip therein. The semiconductor chip includes a plurality of pad electrodes, and the packaging circuit portion includes wiring connected to the pad electrodes on the semiconductor chip, mounting terminals, and a first signal path for receiving a signal output from the predetermined one of the pad electrodes and transmitting the signal to other one of the pad electrodes. The first signal path includes delay elements comparable to delays in a second signal path extending from the predetermined one of the mounting terminals to the other one of the mounting terminals through the semiconductor chip, and is disposed on a feedback path for phase comparison for synchronizing the phase of an output signal from the second signal path to the phase of an input signal to the second signal path.
