    Abstract: The cell has three transistors e.g. vertical transistors formed on the edges (1F1,1F2,2F2) of trenches (G1,G2) separated alternately by smaller and larger gaps. These facilitate the interconnection of source/drain regions (1S/D1,3S/D2, 2S/D2) of different transistors by contact regions (K). A gate electrode (Ga1) of one transistor is connected to a wordline which is to be read (WA), with the second source or drain region (1S/D2) of this transistor being connected to a bitline (B). The gate electrode (Ga3) of a third transistor is connected to a wordline which is to be written to. The first source or drain region (1S/D1) of the reading transistor is connected to both the second source/drain region of the writing transistor and to which a source/drain region (2S/D2) of a further transistor. The gate (Ga2) of this latter transistor is connected to the source/drain (3S/D1) of the writing transistor and its other source/drain is connected to a power supply.

    Abstract: The arrangement has rows and columns separated by trenches (5,6) in a transistor cell field in a substrate, active regions (3) between upper (4) and lower (2) source/drain connection regions forming channels controllable by gate electrode potentials. The active regions join at least transistor cells (81) adjacent in the x-direction and charge transport is enabled between the active regions of transistor cells that are adjacent at least in the x-direction. An independent claim is also included for the following: (a) a method of manufacturing vertical transistor cells in a transistor cell field.

    Abstract: Layers of metallic lines and layers of memory cells are disposed alternately one above the other. The memory cells each have a diode and a memory element connected in series therewith. The memory element has a layer structure with a magnetoresistive effect. The diode has a layer structure containing at least two metal layers and an insulating layer disposed in between. The layer structure of the memory element and the layer structure of the diode are disposed above one another. The metallic lines of a respective one of the layers run parallel to one another. The metallic lines of mutually adjacent layers run transversely with respect to one another.

    Abstract: An integrated circuit having at least two vertical MOS transistors, and method for manufacturing same, wherein first source/drain regions of the two vertical MOS transistors are located in an upper region of sidewalls of a trench. A second source/drain region is shared by both MOS transistors and is adjacent a floor of the trench. Gate electrodes of the MOS transistors that are arranged at the sidewalls of the trench can be individually contacted via parts of a conductive layer that are arranged above the first source/drain regions. In a manufacturing method, such arrangement is made possible by the deposition of a conductive layer of doped polysilicon before the generation of the trench. The area of an MOS transistor can amount to 4F2.
