Abstract
First and second gate electrode layers that are positioned in a first conductive layer, first and second drain-drain contact layers that are positioned in a second conductive layer, and first and second drain-gate contact layers that are positioned in a third conductive layer together form conductive layers for a flip-flop. A sub word line extends in the X-axis direction in the first conductive layer. A V wire is disposed extending in the X-axis direction in the second conductive layer. A main word line is disposed extending in the X-axis direction in the third conductive layer. A bit line, a bit line/, a V wire, and a V wire are disposed extending in the Y-axis direction in the fourth conductive layer.
