    Abstract: A semiconductor device includes: a peripheral circuit region including circuit elements on a substrate, the circuit elements of a page buffer and a row decoder; and a cell region including gate electrode layers, stacked in a first direction, perpendicular to an upper surface of the substrate, and connected to the row decoder, and channel structures extending in the first direction to penetrate through the gate electrode layers and to be connected to the page buffer. The row decoder includes high-voltage elements, operating at a first power supply voltage, and low-voltage elements operating at a second power supply voltage, lower than the first power supply voltage. Among the high-voltage elements, at least one first high-voltage device is in a first well region doped with impurities having a first conductivity-type. At least one of the low-voltage elements is in a second well region surrounding the first well region and doped with impurities having a second conductivity-type, different from the first conductivity-type.

    Abstract: A nonvolatile memory includes; a memory cell array including memory cells commonly connected to a first signal line, a first row decoder including a first pass transistor configured to provide a driving voltage to one end of the first signal line, and a second row decoder including a second pass transistor configured to provide the driving voltage to an opposing end of the first signal line. An ON-resistance of the first pass transistor is different from an ON-resistance of the second pass transistor. A first wiring line having a first resistance connects the first pass transistor and the one end of the first signal line and a second wiring line having a second resistance different from the first resistance connects the second pass transistor and the opposing end of the first signal line.
