Abstract: A transistor comprising threshold voltage control gates. The transistor also comprises active control gates adjacent opposing first sides of a channel region, the threshold voltage control gates adjacent opposing second sides of the channel region, and a dielectric region between the threshold voltage control gates and the channel region and between the active control gates and the channel region. A semiconductor device comprising memory cells comprising the transistor is also disclosed, as are systems comprising the memory cells, methods of forming the semiconductor device, and methods of operating a semiconductor device.

Abstract: The hybrid memory device may include volatile and non-volatile memory cells on a single substrate, or die. The non-volatile memory cells may have ferroelectric capacitors and the volatile memory cells may have paraelectric or linear dielectric capacitors for their respective logic storage components. In some examples, the volatile memory cells may be used as a cache for the non-volatile memory cells. Or the non-volatile memory cells may be used as a back-up for the volatile memory cells. By placing both types of cells on a single die, rather than separate dies, various performance metrics may be improved, including those related to power consumption and operation speed.

Abstract: A method of forming an array of capacitors comprises forming a vertical stack above a substrate. The stack comprises a horizontally-elongated conductive structure and an insulator material directly above the conductive structure. Horizontally-spaced openings are formed in the insulator material to the conductive structure. An upwardly-open container-shaped bottom capacitor electrode is formed in individual of the openings. The bottom capacitor electrode is directly against conductive material of the conductive structure. The conductive structure directly electrically couples the bottom capacitor electrodes together. A capacitor insulator is formed in the openings laterally-inward of the bottom capacitor electrodes. A top capacitor electrode is formed in individual of the openings laterally-inward of the capacitor insulator. The top capacitor electrodes are not directly electrically coupled together. Structure independent of method is disclosed.

Abstract: A memory cell includes a select device and a capacitor electrically coupled in series with the select device. The capacitor includes two conductive capacitor electrodes having ferroelectric material there-between. The capacitor has an intrinsic current leakage path from one of the capacitor electrodes to the other through the ferroelectric material. There is a parallel current leakage path from the one capacitor electrode to the other. The parallel current leakage path is circuit-parallel the intrinsic path and of lower total resistance than the intrinsic path. Other aspects are disclosed.

At least a portion of the gate dielectric comprises ferroelectric material. In some embodiments the ferroelectric material is within each of the first, second and third segments. In some embodiments, the ferroelectric material is within the first segment or the third segment. In some embodiments, a transistor has a gate, a source region and a drain region; and has a channel region between the source and drain regions. The transistor has a gate dielectric which contains ferroelectric material between the source region and the gate.

Abstract: The apparatuses and methods described herein may operate to measure a voltage difference between a selected access line and a selected sense line associated with a selected cell of a plurality of memory cells of a memory array. The voltage difference may be compared with a reference voltage specified for a memory operation. A selection voltage(s) applied to the selected cell for the memory operation may be adjusted responsive to the comparison, such as to dynamically compensate for parasitic voltage drop.
