    摘要: A quantum device functioning as a memory device is provided for allowing high-speed writing and erasing of data with a low gate voltage. A source electrode and a drain electrode are formed on a substrate. A gate electrode is formed between the source and drain electrodes. Between the substrate and the gate electrode, a first barrier layer, a first quantum well layer, a second barrier layer, a second quantum well layer and a third barrier layer are stacked to form coupled quantum well layer. The thickness of each of the first and second barrier layers allows electron tunneling. The thickness of the third barrier layer does not allow electron tunneling. The energy level of the first quantum well layer is higher than the Fermi level of a conduction layer. The energy level of the second quantum well layer is lower than the energy level of the first quantum well layer. With an application of voltage to the gate electrode, a transition of electrons takes place by means of tunneling through the first quantum well layer to the second quantum well layer and the electrons are accumulated therein.

    摘要: A semiconductor memory device comprises a non-doped thick barrier layer formed on the semiconductor substrate, an impurity doped floating conducting layer formed on the thick barrier layer, a thin barrier layer formed on the floating conducting layer and having an asymmetric barrier whose barrier height is higher on the side of the floating conducting layer, a channel layer formed on the thin barrier layer, and a first electrode and a second electrode formed on the channel layer. A write bias voltage which makes a potential of the second electrode higher than that of the first electrode is applied so as to inject electrons from the first electrode to the floating conducting layer through the thin barrier layer, thereby writing information in the floating conducting layer. A read bias voltage lower than the write bias voltage is applied between the first and the second electrodes, and the information stored in the floating conducting layer is read based on whether or not a current flows in the channel layer.
