Abstract:
Virtual ground sensing circuits, electrical systems, computing devices, and related methods are disclosed. A virtual ground sensing circuit includes a sense circuit configured to compare a reference voltage potential to a sense node voltage potential, and virtual ground circuitry operably coupled to the sense circuit. The virtual ground circuitry is configured to provide a virtual ground at a first bias voltage potential to a conductive line operably coupled to a selected ferroelectric memory cell, and discharge the conductive line to the sense node responsive to the selected ferroelectric memory cell changing from a first polarization state to a second polarization state. A method includes applying a second bias voltage potential to another conductive line operably coupled to the selected ferroelectric memory cell, and comparing a sense node voltage potential to a reference voltage potential. Electrical systems and computing devices include virtual ground sensing circuits.

Claim (Index 21):
A method of operating an electrical system, the method comprising:\n applying, with biasing circuitry, a critical voltage potential to a selected ferroelectric memory cell in an array of ferroelectric memory cells through a pair of conductive lines operably coupled to the selected ferroelectric memory cell, wherein the critical voltage potential is selected to cause the selected ferroelectric memory cell to switch from a first polarization state to a second polarization state; and discharging, with virtual ground sensing circuitry operably coupled to one of the pair of conductive lines, charge that is at least one of sinked to and emitted from the selected ferroelectric memory cell to a sense node if the selected ferroelectric memory cell switches from the first polarization state to the second polarization state, wherein the sense node has a sense node capacitance that is less than a capacitance of the one of the pair of conductive lines.
