Abstract:
A memory device comprising a base; a capacitor comprising a ferroelectric layer and at least two electrically conductive layers, the ferroelectric layer being located between the at least two electrically conductive layers; each of the at least two conductive layers being operatively connected to a current source; a cantilever attached to the base at first end and movable at a second end, the ferroelectric capacitor being mounted to the cantilever such that the second end of the cantilever moves a predetermined displacement upon application of a current to the ferroelectric layer which induces deformation of the ferroelectric layer thereby causing displacement of the cantilever which is operatively associated with a contact so that an electrical connection is enabled with the contact upon the predetermined displacement of the cantilever. The presence or absence of a connection forms two states of a memory cell.
