1. An integrated circuit (IC) comprising:
a first column comprising a plurality of first power rails, each first power rail of the plurality of first power rails being configured to provide a first supply voltage or a second supply voltage to a plurality of first cells and extending in a first horizontal direction with a first pitch;
a second column comprising a plurality of second power rails configured to provide the first supply voltage or the second supply voltage to a plurality of second cells and extending in the first horizontal direction with a second pitch different from the first pitch; and
an interface column extending in a second horizontal direction perpendicular to the first horizontal direction between the first column and the second column,
wherein the interface column comprises a first power line extending in the second horizontal direction,
wherein the first power line is connected to a first group of the plurality of first power rails configured to provide the first supply voltage, and
wherein each power rail of the plurality of first power rails and the plurality of second power rails comprises at least one of:
a second conductive pattern buried in a substrate and extending in the first horizontal direction;
a source/drain contact extending in the first horizontal direction; and
a third conductive pattern extending in the first horizontal direction in a first wiring layer.
