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.

摘要:
A conjugated polymer layer with a built-in diode is formed by providing a first metal-chalcogenide layer over a bottom electrode. Subsequently, a second metal-chalcogenide layer is provided over and in contact with the first metal-chalcogenide layer. The first metal-chalcogenide layer has a first conductivity type and the second metal-chalcogenide layer has a second conductivity type. The plane of contact between the first and second metal-chalcogenide layers creates the p-n junction of the built-in diode. Then a polymer layer is selectively deposited on the second metal-chalcogenide layer. The second metal-chalcogenide layer provides ions to the polymer layer to change its resistivity. A top electrode is then provided over the polymer layer. An exemplary memory cell may have the following stacked structure: first electrode/n-type semiconductor/p-type semiconductor/conjugated polymer/second electrode.
