Abstract: An integrated circuit includes a first switching device including a first semiconductor region in a first section of a semiconductor portion and a second switching device including a second semiconductor region in a second section of the semiconductor portion. The first and second sections as well as electrode structures of the first and second switching devices outside the semiconductor portion are arranged along a vertical axis perpendicular to a first surface of the semiconductor portion.

Abstract: Embodiments relate to bootstrap circuits integrated with at least one other device, such as a power transistor or other semiconductor device. In embodiments, the bootstrap circuit can comprise a bootstrap capacitor and a bootstrap diode, or the bootstrap circuit can comprise a bootstrap capacitor and a bootstrap transistor. The bootstrap capacitor comprises a semiconductor-based capacitor, as opposed to an electrolytic, ceramic or other capacitor, in embodiments. The integration of the bootstrap circuit with another circuit or device, such as a power transistor device in one embodiment, is at a silicon-level in embodiments, rather than as a module-like system-in-package of conventional approaches. In other words, the combination of the bootstrap circuit elements and power transistor or other device forms a system-on-silicon, or an integrated circuit, in embodiments, and additionally can be arranged in a single package.

Abstract: A circuit includes a first negative feed back loop coupled to a virtual Vvdd power rail and a true Vdd power rail. A second negative feed back loop is coupled to the virtual Vvss power rail and a true Vss power rail. The virtual rail to virtual rail voltage difference is regulated at the highest threshold voltage between pull-up and pull-down transistors of a memory cell.
