Arrangement and method to perform scanning readout of ferroelectric bit charges
Abstract:
An arrangement, a method and a system to read information stored in a layer of ferroelectric media. The arrangement includes a layer including a ferroelectric media having one or more ferroelectric domains holding bit charges, a domain corresponding to information; a probe having a tip, wherein the media and the tip are adapted to move relative to one another such that the tip scans the ferroelectric domains of the media while applying a contact force to the domains to generate a direct piezoelectric effect within the domains; and circuitry coupled to the tip and adapted to generate a signal in response to an electrical coupling between the tip and the domains while scanning the tip in contact with the domains, the signal corresponding to a readout signal for ferroelectric bit charges stored in the media.
