Abstract
The present invention provides a semiconductor device and a method for manufacturing thereof. The semiconductor device includes a data storage element which includes a variable resistance and an electrode, and a controller which selects a first mode that stores data by the resistance value of the variable resistance and a second mode that stores data by the amount of electrical charges stored in the electrode. By selectively using the data storage element in the first mode and the second mode, a plurality of storage modes can be implemented with a single data storage element. Thus, miniaturization and cost reduction of the semiconductor device can be achieved.
