Abstract: A semiconductor device includes first, second, and third power rails extending in a first direction on a substrate and sequentially spaced apart in a second direction intersecting the first direction. A fourth power rail extends in the first direction on the substrate between the first and third power rails. A first well of a first conductive type is displaced inside the substrate between the first and third power rails. Cells are continuously displaced between the first and third power rails and share the first well. The first and third power rails are provided with a first voltage, the second power rail is provided with a second voltage different from the first voltage, the fourth power rail is provided with a third voltage different from the first voltage and the second voltage, and the cells are provided with the third voltage from the fourth power rail.

Abstract: A semiconductor circuit includes a first circuit, a second circuit, a third circuit, and a fourth circuit. The first circuit determines a value of a first node based on a voltage level of a clock signal, and a voltage level of an enable signal or a voltage level of a scan enable signal. The second circuit determines a value of a second node based on the voltage levels of the first node and the clock signal. The third circuit determines a value of a third node based on a voltage level of the second node. The fourth circuit determines a value of a fourth node based on the voltage levels of the second node and the clock signal. The third circuit includes a first transistor and a second transistor connected in series with each other and gated to the voltage level of the second node to determine the value of the third node. The fourth circuit includes a third transistor that is gated to the voltage level of the clock signal to electrically connect the third node and the fourth node.
