Patent ID: 8743586

Claim:
An electrometric access head, comprising: a supporting substrate; and a plurality of read elements mounted on said supporting substrate, each said read element comprising an electrometric sensor for a detection of a sign of polarization of domains within a ferroelectric data layer of a ferroelectric storage medium, said ferroelectric data layer serving as a layer for storing information as bits defined by said signs of polarization of domains within said ferroelectric data layer, each polarized domain comprising a volume dipole polarization within said ferroelectric data layer and including an area of bound charge on and adjacent to a surface of said ferroelectric data layer, wherein each said read element comprises a FinFET transistor and an axis channel length of each said FinFET transistor is approximately 20 nanometers (nm) and a width of said FinFET channel is approximately 10 nm”; and.
