    摘要: Bitline conductor tracks are arranged parallel to one another and electrically insulated from a substrate provided with a basic doping. A memory layer sequence, especially a charge-trapping layer sequence with a dielectric memory layer between dielectric confinement layers, is provided at least in regions adjacent to the bitline conductor tracks. The memory cells comprise gate electrodes connected by wordlines, and channel regions below the gate electrodes. They can be programmed by the trapping of channel hot electrons that are accelerated between source and drain regions formed by induced bitlines that are generated by the application of voltages to the bitline conductor tracks.

    摘要: To manufacture a memory device, a gate dielectric layer is formed over a semiconductor body and a gate electrode layer is formed over the gate dielectric layer. The gate electrode layer is structured to form a gate electrode with sidewalls. An etching process is performed to remove parts of the gate dielectric layer from beneath the gate electrode on opposite sides of the gate electrode. Boundary layers, e.g., oxide layers, are formed on an upper surface of the semiconductor body and a lower surface of the gate electrode adjacent where the gate dielectric has been removed thereby leaving spaces. Charge-trapping layer material can then be deposited to fill the spaces. Source and drain regions are then formed in the semiconductor body adjacent the gate electrode.

    摘要: A memory cell array comprises a plurality of memory transistors arranged in a two-dimensional array, each memory transistor having two source/drain regions arranged in a first direction of the memory cell array with a channel substrate region therebetween, and a gate structure arranged above the channel substrate region. The source/drain regions and channel substrate regions are formed in a substrate arranged on an insulating layer, with the channel substrate regions of memory transistors adjacent each other in the first direction being separated from each other by respective source/drain regions extending down to the insulating layer. The source/drain regions and the channel substrate regions of memory transistors adjacent each other in a second direction of the memory cell array furthermore are isolated from each other by trenches filled with insulating material and formed in the substrate so as to extend down to the insulating layer.

    摘要: A memory cell includes a channel region between source/drain regions at the top side of a semiconductor body and is provided, transversely with respect to the longitudinal direction, with a bulge formed in the semiconductor material. This results in a uniform distribution of the strength of a radially directed electric field and avoids field strength spikes at lateral edges of the channel region. A storage layer sequence is situated between the channel region and the gate electrode as part of a word line.
