Abstract
An integrated circuit includes a transistor formed in a semiconductor structure, a front-side horizontal conducting line in a first metal layer above the semiconductor structure, and a front-side vertical conducting line in a second metal layer above the first metal layer. The front-side horizontal conducting line is directly connected to a first terminal of the transistor, and the front-side vertical conducting line is directly connected to the front-side horizontal conducting line. In the integrated circuit, a front-side fuse element is conductively connected to the front-side vertical conducting line, and a backside conducting line is directly connected to a second terminal of the transistor. A word connection line extending in the first direction is directly connected to a gate terminal of the transistor.
