摘要:
A method of incorporating oxygen vacancies near an electrode/oxide interface region of a complex metal oxide programmable memory cell which includes forming a first electrode of a metallic material which remains metallic upon oxidation, forming a second electrode facing the first electrode, forming an oxide layer in between the first and second electrodes, applying an electrical signal to the first electrode such that oxygen ions from the oxide layer are embedded in and oxidize the first electrode, and forming oxygen vacancies near the electrode/oxide interface region of the complex metal oxide programmable memory cell.

The present invention relates to a memory cell comprising: a resistive structure; at least two electrodes coupled to the resistive structure, and at least one hydrogen reservoir structure, wherein the application of an electrical signal to one of the at least two electrodes causes the electrical resistance of the resistive structure to be modified by altering a hydrogen-ion concentration in the resistive structure.

A non-volatile programmable electro-optical element alters absorption characteristics of an optical medium that comprises a doped transition metal oxide material including F-centers. The F-centers are electrostatically moved into or out of the regions containing a wavefunction of an optical beam. A specific F-center profile in the transition metal oxide material may be programmed into the optical medium. The F-center profile alters an absorption profile within the optical medium. The spectral range for transmission of electromagnetic radiation in the optical medium may be tailored by the F-centers. Once the absorption profile is set by an electrical signal, the optical element maintains its state even when the electrical signal is turned off. Thus, the programming node may be disconnected from a power supply network, thereby enabling a low power operation of the electro-optical element. The inventive electro-optical element may be employed for both the visible and the infrared wavelength spectrum.

Disclosed are a semiconductor structure and a method that allow for simultaneous voltage/current conditioning of multiple memory elements in a nonvolatile memory device with multiple memory cells. The structure and method incorporate the use of a resistor connected in series with the memory elements to limit current passing through the memory elements. Specifically, the method and structure incorporate a blanket temporary series resistor on the wafer surface above the memory cells and/or permanent series resistors within the memory cells. During the conditioning process, these resistors protect the transition metal oxide in the individual memory elements from damage (i.e., burn-out), once it has been conditioned.

A field effect device includes a source electrode, a drain electrode, a channel formed between the source electrode and the drain electrode, and a gate electrode formed directly on the channel and arranged in a gap between the source electrode and the drain electrode. The channel includes a switching material that is reversibly switchable between a lower conductivity state and a higher conductivity state. The first conductivity state has an electrical conductivity which is lower than an electrical conductivity of the second conductivity state. Each of the conductivity states is persistent without the need for a sustaining excitation signal including an electrical field, heat and/or light applied to the device.

Thus, the programming node may be disconnected from a power supply network, thereby enabling a low power operation of the electro-optical element. Amorphous transition-metal oxides enable integration into back-end-of-line (BEOL) interconnect structures and do not have birefringence. The inventive electro-optical element may be employed for both the visible and the infrared wavelength spectrum.
摘要:
Disclosed are non-volatile memory devices that incorporate a series of single or double memory cells. The single memory cells are essentially “U” shaped. The double memory cells comprise two essentially “U” shaped memory cells. Each memory cell comprises a memory element having a bi-stable layer sandwiched between two conductive layers. A temporary conductor may be applied to a series of cells and used to bulk condition the bi-stable layers of the cells. Also, due to the “U” shape of the cells, a cross point wire array may be used to connect a series of cells. The cross point wire array allows the memory elements of each cell to be individually identified and addressed for storing information and also allows for the information stored in the memory elements in all of the cells in the series to be simultaneously erased using a block erase process.

Each pair of memory modules in a memory system are cooled using a shared cooling pipe, such as a heat pipe or liquid flow pipe. An example embodiment includes one pair of memory module sockets on opposite sides of the respective cooling pipe. An inner heat spreader plate is thermally coupled to the cooling pipe and in thermal engagement with a first face of the memory module adjacent to the included cooling pipe. Heat is conducted from the second face of the memory module to the cooling pipe, such as from an outer plate in thermal engagement with an opposing second face of the memory modules and with the inner plate.
