An integrated circuit includes a first conductive layer and a first insulation layer formed on the first conductive layer. The integrated circuit also includes a second insulation layer formed on the first insulation layer and a second conductive layer formed on the second insulation layer. The first insulation layer may include a first defect, and the second insulation layer may include a second defect. The integrated circuit may also include a third insulation layer formed on the second conductive layer, a fourth insulation layer formed on the third insulation layer, and a third conductive layer formed on the fourth insulation layer. The third insulation layer may include a third defect, and the fourth insulation layer may include a fourth defect.
