In another embodiment, the second horizontal line VL2h and the second vertical line VL2v may be provided in the same layer. In other words, the second horizontal line VL2h and the second vertical line VL2v may be in direct contact with each other. In this case, the fourth contact plug CP4 may correspond to a portion where the second horizontal line VL2h and the second vertical line VL2v are in contact with each other. In other words, the fourth contact plug CP4 may correspond to a portion where the second horizontal line VL2h and the second vertical line VL2v cross each other.
