Patent number: 8054669Abstract: 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.Type: GrantFiled: August 12, 2008Date of Patent: November 8, 2011Assignee: International Business Machines CorporationInventors: Gerhard I.

Patent number: 7834384Abstract: 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.Type: GrantFiled: April 2, 2008Date of Patent: November 16, 2010Assignee: International Business Machines CorporationInventors: Toshijaru Furukawa, Mark C.

Patent number: 7580596Abstract: A non-volatile programmable electro-optical element alters absorption characteristics of an optical medium that comprises a transition metal oxide material by electrostatically moving oxygen vacancies into or out of the regions containing a wavefunction of an optical beam. A specific oxygen vacancy profile in the transition metal oxide material may be programmed into the optical medium. The oxygen vacancy profile alters an absorption profile within the optical medium. 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. 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.Type: GrantFiled: August 12, 2008Date of Patent: August 25, 2009Assignee: International Business Machines CorporationInventors: Gerhard I.

Patent number: 7541608Abstract: 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.Type: GrantFiled: February 14, 2008Date of Patent: June 2, 2009Assignee: International Business Machines CorporationInventors: Toshijaru Furukawa, Mark C.
