Abstract:
1. A non-volatile variable capacitive device, comprising: a device disposed upon a substrate including a gate and a gate oxide disposed above the substrate, wherein a first capacitive device is defined over the substrate, and wherein the gate is an upper electrode of the first capacitive device; and a resistive memory cell having a first electrode, a second electrode, and a switching layer provided between the first and second electrodes, wherein the resistive memory cell is configured to be placed in first and second resistive states in response to electrical signals applied thereto, wherein the resistive memory cell is configured to behave substantially as a resistor in the first state and substantially as a second capacitive device in the second state, wherein the upper electrode of the first capacitive device is coincident to the second electrode of the resistive memory cell, and wherein the resistive memory cell comprises a two-terminal device.
