ABSTRACT:
An information storage device includes a ferroelectric layer having a first surface and a second surface opposite the first surface. A common electrode layer is formed on the first surface of the ferroelectric layer. At least two conductive track layers separated from each other are positioned on the second surface of the ferroelectric layer. A conductive roller that has two opposite ends supported by the conductive track layers is provided. The conductive roller is movable along a conductive track. A ferromagnetic layer creates a magnetic field on the conductive roller.
