    Abstract: The invention relates to a semiconductor memory having a multiplicity of memory cells and a method for forming the memory cells. The semiconductor memory generally includes a semiconductor layer arranged on a substrate surface that includes a normally positioned step between a deeper region and a higher region. The semiconductor memory further includes doped contact regions, channel regions, a trapping layer arranged on a gate oxide layer, and at least one gate electrode. The method for forming the memory cells includes patterning a semiconductor layer to form a deeper semiconductor region and a higher semiconductor region having a step positioned between the regions. The method further includes forming a first oxide layer and a trapping layer, and then removing portions of the trapping layer and the first oxide layer and applying a second oxide layer at least regions of a doped region, the trapping layer, and the step area, and applying a gate electrode to the second oxide layer and doping, at least in regions, of the deeper semiconductor region and the higher semiconductor region to form a deeper contact region and a higher contact region.

    Abstract: A dual-gate MOSFET semiconductor layer structure is constructed on a substrate (1). Said semiconductor layer structure consists of a first gate electrode and a second gate electrode (10A, 10B), between which a semiconductor channel layer area (4A) is embedded, and a source area (2A) and a drain area (2B), which are situated on opposite front sides of the semiconductor channel layer area (4A). At least one other semiconductor channel layer area (6A) is provided at one of the gate electrodes (10B), the front sides of this semiconductor channel layer area (6A) also being contacted by the source (2A) and drain (2B) areas.
