Abstract: Methods, systems, and devices for self-referencing sensing schemes with coupling capacitance are described. A sense component of a memory device may include a capacitive coupling between two nodes of the sense component. The capacitive coupling may, in some examples, be provided by a capacitive element of the sense component or an intrinsic capacitance between features of the sense component. An example of a method employing such a sense component for detecting a logic state stored by a memory cell may include generating a first sense signal at one of the nodes while the node is coupled with the memory cell, and generating a second sense signal at the other of the nodes while the other node is coupled with the memory cell. The sense signals may be based at least in part on the capacitive coupling between the two nodes.

Abstract: In some examples, an electronic device comprising an input ferroelectric (FE) capacitor, an output FE capacitor, and a channel positioned beneath the input FE capacitor and positioned beneath the output FE capacitor. In some examples, the channel is configured to carry a magnetic signal from the input FE capacitor to the output FE capacitor to cause a voltage change at the output FE capacitor. In some examples, the electronic device further comprises a transistor-based drive circuit electrically connected to an output node of the output FE capacitor. In some examples, the transistor-based drive circuit is configured to deliver, based on the voltage change at the output FE capacitor, an output signal to an input node of a second device.
