  • Semiconductor device and electronic apparatus
    Patent number: 10222272
    Abstract: In one embodiment, a semiconductor device (20) includes a semiconductor chip (200) in which functional blocks (201, 202, 203 etc.) and a temperature sensor (208) are integrated. In this embodiment, in response to a change in an operation state of the semiconductor device (20), the on-chip temperature sensor (208) operates to switch from a continuous operation in which it continuously measures a chip temperature to an intermittent operation in which it intermittently measures the chip temperature, or to change a time interval between intermittent measurements of the chip temperature.
    Type: Grant
    Filed: July 24, 2012
    Date of Patent: March 5, 2019
    Assignee: Renesas Electronics Corporation
    Inventors: Chiaki Kumahara, Akira Tsurugasaki
