A method for operating a memory device includes applying a sequence of bias arrangements across a selected metal-oxide memory element to change among resistance states. The sequence of bias arrangements includes a first set of one or more pulses to change the resistance state of the selected metal-oxide memory element from the first resistance state to a third resistance state, and a second set of one or more pulses to change the resistance state of the selected metal-oxide memory element from the third resistance state to the second resistance state.

An example of a capacitor includes a series of ridges and trenches and an interconnect region on the integrated circuit substrate. The series of ridges and trenches and the interconnect region have a capacitor foundation surface with a serpentine cross-sectional shape on the series of ridges and trenches. Electrical conductors are electrically connected to the electrode layers from the interconnect region for access to the electrode layers of the capacitor assembly.

A magnetic memory device comprises a magnetic memory cell that includes a pinned layer and a free layer separated from the pinned layer by an insulating layer. The magnetic memory device also comprises a thermal plate in contact with the free layer. The magnetic memory device can be configured so that a first current flows through the thermal plate heating the thermal plate. The magnetic behavior of the free layer can be altered due to the heating caused by the first current, making it easier to switch the orientation and magnetization of the free layer. A second current can then flow through a bit line near the free layer generating a magnetic field sufficient to switch the orientation of magnetization of the free layer.

A non-volatile memory cell is described. The non-volatile memory cell comprises a substrate, a charge-trapping layer, a gate and a source/drain. The charge-trapping layer comprises an insulating layer and metal nano-particles contained therein, wherein the metal nano-particles are formed with thermal dissociation of an oxide of the same metal. The gate is disposed on the charge-trapping layer, and the source/drain is located in the substrate beside the gate.
