摘要： The present invention is to provide a semiconductor memory device capable of providing excellent storage properties, scaling and high integration and a method of fabricating the same. A semiconductor memory device has a multiferroic film exhibiting ferroelectricity and ferromagnetism, a channel region on an interface of a semiconductor substrate below the multiferroic film, source and drain regions formed on both sides of the channel region, a gate electrode (data write electrode) applying gate voltage to the multiferroic film to write data in such a way that the orientation of magnetization is changed as corresponding to the orientation of dielectric polarization, and source and drain electrodes (data read electrodes) that read data based on a deviation in a flow of the carrier, the deviation caused by applying the Lorentz force to the carrier flowing in the channel region from a magnetic field occurring in the channel region because of magnetization.
