Standard cell and an integrated circuit including the same

An integrated circuit, comprising:

• first and second standard cells arranged in a first horizontal direction;
• a power rail comprising first and second conductive lines spaced apart from each other in a vertical direction, wherein the first and second conductive lines extend in parallel in the first horizontal direction, and are electrically connected to each other, to supply power to the first and second standard cells, wherein the first and second conductive lines are disposed at a boundary of each of the first and second standard cells;
• and
• a third conductive line between the first and second conductive lines and extended in a second horizontal direction orthogonal to the first horizontal direction, to transfer an input signal or an output signal of the first standard cell,
• wherein the power rail further comprises a fourth conductive line extending in the first horizontal direction on the boundary of the second standard cell, wherein the fourth conductive line is electrically connected to the first and second conductive lines, and is formed in a same layer as the third conductive line.

An integrated circuit, comprising:
