  • Patent number: 11100962
    Abstract: A semiconductor device includes a power gating control block and a power gating circuit. The power gating control block activates a data power control signal during a period that is set by a target code, the period being from a point in time in which the semiconductor device enters a read mode or a write mode. In addition, the power gating control block deactivates an operation power control signal in a power-down mode. The power gating circuit inhibits a data power signal from being supplied to a data input/output block based on the data power control signal. Moreover, the power gating control block inhibits an operation power signal from being supplied to an internal operation control block based on the operation power control signal.

  • Patent number: 11023065
    Abstract: In one embodiment, a touch sensor includes a first electrode, a second electrode, and a spacer layer located between the first electrode and the second electrode. One of the first electrode and the second electrode is a drive electrode to which a drive signal is applied. The other one of the first electrode and the second electrode is a receiving electrode that receives the drive signal by a mutual capacitance between the first electrode and the second electrode. When an external pressure is applied to the first electrode through a display, the first electrode is concavely bent toward the second electrode. The mutual capacitance between the first electrode and the second electrode changes according to a distance between the first electrode and the second electrode. The magnitude of the external pressure according to the change of the capacitance between the first electrode and the second electrode is detected.
