  • Semiconductor device and integrated semiconductor device
    Patent number: 8659018
    Abstract: The present disclosure provides a semiconductor device including: a semiconductor identifier holding portion configured to hold a semiconductor identifier for identifying a semiconductor device; and a control portion configured such that upon elapse of a predetermined time period following receipt of an externally input instruction to hold the semiconductor identifier, the control portion issues an instruction to the semiconductor device immediately downstream of the semiconductor device to hold a semiconductor identifier of the immediately downstream semiconductor device and that during the time period between the point in time at which the externally input instruction is received and the point in time at which the instruction is issued to the immediately downstream semiconductor device to hold the semiconductor identifier thereof, the control portion causes the semiconductor identifier holding portion to hold the externally input identifier.
    Type: Grant
