    Abstract: To provide a semiconductor device which can be stably operated while achieving a reduction of the power consumption.
    A semiconductor device includes a CPU, a system controller which designates an operation speed of the CPU, P-type SOTB transistors, and N-type SOTB transistors. The semiconductor device is provided with an SRAM which is connected to the CPU, and a substrate bias circuit which is connected to the system controller and is capable of supplying substrate bias voltages to the P-type SOTB transistors and the N-type SOTB transistors. Here, when the system controller designates a low speed mode to operate the CPU at a low speed, the substrate bias circuit supplies the substrate bias voltages to the P-type SOTB transistors and the N-type SOTB transistors.

    Abstract: The semiconductor device controls the first circuit for supplying/stopping the current supplied by a DC power supply to the latching solenoid consisting of a coil and a movable iron core and a permanent magnet, the current is measured based on the input from the current detection circuit. The semiconductor device includes a control circuit having a low power dissipation mode in which the leakage current is reduced, and a normal operation mode. The control circuit maintains the low power consumption mode when no current is flowing through the coil, when a current is flowing through the coil maintains the normal operation mode, further, the movable iron core It comprises a control circuit configured to detect the inflection point of the current detected by the current detection circuit when leaving the permanent magnet.
