  • Semiconductor module
    Patent number: 6708302
    Abstract: A semiconductor module that comprises a plurality of semiconductor chips mounted on a single substrate and which readily diagnoses all the semiconductor chips. A plurality of semiconductor chips are mounted on a single substrate. The semiconductor module is provided with a mode signal pin for receiving a mode signal for requesting performance of a diagnostic operation, as well as with a result output pin for outputting diagnostic results. Further, each of the semiconductor chips is provided with a diagnostic circuit for diagnosing the status of the corresponding semiconductor chip. The semiconductor module is also provided with a diagnosis controller for controlling the diagnostic circuits such that all the semiconductor chips are diagnosed in parallel or serially after a mode signal for requesting a diagnostic operation has been supplied to the mode signal pin.
