    摘要: The SRAM cell configuration has at least six transistors in each memory cell. Four of the transistors form a flip-flop and they are arranged at the corners of a quadrilateral. The flip-flop is driven by two of the transistors, which are disposed so as to adjoin diagonally opposite corners of the quadrilateral and outside the quadrilateral. Adjacent memory cells along a word line can be arranged in such a way that a first bit line and a second bit line of the adjacent memory cells coincide. The transistors are preferably vertical and are arranged at semiconductor structures (St1, St2, St3, St4, St5, St6) produced from a layer sequence. Two of the transistors having n-doped channel regions are preferably formed in each case on two semiconductor structures.

    摘要: In a read-only memory cell arrangement having first memory cells which contain a vertical MOS transistor, and having second memory cells which do not contain vertical MOS transistors, the memory cells are arranged along opposite flanks of strip-shaped parallel insulation trenches (16). The width of the insulation trenches (16) is preferably equal to their separation, so that the memory cell arrangement can be produced with a space requirement of 2F.sup.2 per memory cell, F being the minimum structure size in the respective technology.

    摘要: An electrically writable and erasable read-only memory cell arrangement fabricated in a semiconductor substrate, preferably of monocrystalline silicon, or in a silicon layer of an SOI substrate. A cell array with memory cells is provided on a main surface of the semiconductor substrate. Each memory cell comprises an MOS transistor, vertical to the main surface and comprising, in addition to the source/drain region and a channel region arranged in-between, a first dielectric, a floating gate, a second dielectric and a control gate. A plurality of essentially parallel strip-shaped trenches are provided in the cell array. The vertical MOS transistors are arranged on the flanks of the trenches. The memory cells are in each case arranged on opposite flanks of the trenches.

    摘要: Each memory cell of an array has a single-electron transistor and a single-electron memory element. The single-electron transistor is driven by a charge stored in the memory element. When a read voltage is applied, a current flows through the single-electron transistor which is dependent on the stored charge, but the stored charge in not changed. When a write voltage is applied, the magnitude of which is greater than the read voltage, then the stored charge is changed. The memory cells of the array are each connected between first lines and transverse second lines of a memory cell configuration.

    摘要: To make a contact between a capacitor electrode (13) disposed in a trench (11) and an MOS transistor source/drain region disposed outside the trench, a shallow etching is carried out in a self-aligned manner with respect to a field-oxide region insulating the MOS transistor by producing the trench (11) in a substrate (1). After forming an Si.sub.3 N.sub.4 spacer (10) at the edge (8), laid bare during the etching, of the substrate (1) the part laid bare of the field-oxide region (2) is first removed with the aid of a mask and the trench (11) is completed in a further etching. The contact is produced after the formation of an SiO.sub.2 layer (12) at the surface of the trench (11) after removing the Si.sub.3 N.sub.4 spacer (10) and producing the capacitor electrode (13) at the edge (8), laid bare by removing the Si.sub.3 N.sub.4 spacer (10), of the substrate (1).

    摘要: The DRAM cell arrangement comprises, per memory cell, a vertical MOS transistor whose first source/drain region is connected to a storage node of a storage capacitor, whose channel region (3) is annularly enclosed by a gate electrode (13) and whose second source/drain region is connected to a buried bit line. The DRAM cell arrangement is produced using only two masks, with the aid of a spacer technique, with a memory cell area of 2F.sup.2, where F is the minimum structure size which can be produced using the respective technology.

    摘要: A method for production of a read-only-memory cell arrangement having vertical MOS transistors is provided. In order to produce a read-only-memory cell arrangement which has first memory cells having a vertical MOS transistor and second memory cells which do not have a vertical MOS transistor, holes provided with a gate dielectric and a gate electrode are etched in a silicon substrate with a layer sequencing corresponding to a source, a channel and a drain for the first memory cells. Insulation trenches whose separation is preferably equal to their width are produced for insulation of adjacent memory cells.
