Abstract:
1. An integrated circuit that includes at least two memory cells, the integrated circuit comprising: a substrate having a main processing surface; two first electrodes, wherein each of the two first electrodes has a side surface being arranged at a respective angle with regard to the main processing surface, the side surfaces facing one another, the two first electrodes comprising first electrodes of two neighboring memory cells; a second electrode, the second electrode being arranged partially between the side surfaces of the two first electrodes facing one another, the second electrode comprising a common second electrode for both of the two neighboring memory cells; ion conducting material between each of the two first electrodes and the second electrode, and a metallic layer disposed over the ion conducting material and the second electrode, wherein a first portion of the metallic layer is disposed over the main processing surface and remaining portions of the metallic layer are disposed parallel to the side surfaces of the two first electrodes facing one another.
