Abstract
A first lower interconnection structure and a second lower interconnection structure are formed using a first design rule on a first region of a substrate and a second region of the substrate, respectively. A memory element is formed on the first lower interconnection structure. The memory element includes a bottom electrode, a magnetic tunnel junction and a top electrode stacked on each other. An upper conductive line and an upper interconnection line are formed using a second design rule larger than the first design rule on the first lower interconnection structure and the second lower interconnection structure, respectively. The first lower interconnection structure, the memory element and the upper conductive line are stacked on each other so that the memory element is interposed between the first lower interconnection structure and the upper conductive line.
