Patent number: 7465956Abstract: The present invention provides a multi-layer organic memory device that can operate as a non-volatile memory device having a plurality of stacked and/or parallel memory structures constructed therein. A multi-cell and multi-layer organic memory component can be formed with two or more electrodes having a selectively conductive media between the electrodes forming individual cells, while utilizing a partitioning component to enable stacking of additional memory cells on top of or in association with previously formed cells. Memory stacks can be formed by adding additional layers—respective layers separated by additional partitioning components, wherein multiple stacks can be formed in parallel to provide a high-density memory device.Type: GrantFiled: October 17, 2005Date of Patent: December 16, 2008Assignee: Advanced Micro Devices, Inc.Inventors: Nicholas H.

Patent number: 7294849Abstract: An OLED includes a wide gap inert host material doped with two dopants. One of the dopants is an emissive phosphorescent material that can transport either electrons or holes. The other dopant is a charge carrying material that can transport whichever of the electrons and holes that is not transported by the phosphorescent dopant. The materials are selected so that the lowest triplet energy level of the host material and the lowest triplet energy level of the charge carrying dopant material are each at a higher energy level than the lowest triplet state energy level of the phosphorescent dopant material. The device is capable, in particular, of efficiently emitting light in the blue region of the visible spectrum.Type: GrantFiled: March 13, 2002Date of Patent: November 13, 2007Assignees: The Trustees of Princeton University, The University of Southern CaliforniaInventors: Mark E.
