摘要： For the operation of a memory cell arrangement with MOS transistors as memory cells that comprise a dielectric triple layer (5) with a first silicon oxide layer (51), a silicon nitride layer (52) and a second silicon oxide layer (53) as gate dielectric, whereby the silicon oxide layers are respectively at least 3 nm thick, a first cutoff voltage value is allocated to a first logical value and a second cutoff voltage value of the MOS transistor is allocated to a second logical value for storing digital data. The information stored in the memory cell can be modified by applying corresponding voltage levels, although a complete removal of charge stored in the silicon nitride layer is not possible because of the thickness of the silicon oxide layers. What is exploited when modifying the cutoff voltage is that the electrical field in the dielectric triple layer is distorted by charge stored in the silicon nitride layer.

摘要： In a method for manufacturing an electrically writeable and erasable ad-only memory cell arrangement, by self-adjusting process steps, a read-only memory cell arrangement having memory cells that respectively comprise an MOS transistor with a floating gate is manufactured. The MOS transistors are arranged in rows that run parallel. Adjacent rows thus respectively run alternately on the bottom of longitudinal trenches and between adjacent longitudinal trenches. The control gates laterally surround the floating gates so that the memory cells on the bottom of the longitudinal trenches also comprise a coupling ratio>1. A surface requirement per memory cell of 2F.sup.2 (F minimum structural size) is achieved.

摘要： Parallel lines, for example bit lines in a memory cell configuration formed of doped regions in a semiconductor substrate, are driven by electrically connecting a number of the lines to one another and to a common node. A number of selection lines extend transversely to the lines. MOS transistors are arranged at the points of intersection and are connected in series along one of the lines. The gate electrode of the MOS transistors is formed by the corresponding selection line. At least one MOS transistor in each of the parallel lines has a higher threshold voltage than the others.

摘要： For the manufacture of a memory cell arrangement with first memory cells that comprise a vertical MOS transistor and with second memory cells that do not comprise an MOS transistor, whereby the memory cells are arranged along opposite edges of strip-type trenches, memory cells that are adjacent along the trenches (5) are manufactured successively. The spacing of adjacent memory cells is determined in particular by means of a spacer technology. By this means, a space requirement per memory cell of 1F.sup.2 can be realized, whereby F is the minimum structural size of the respective technology.

摘要： An integrated circuit contains a planar first transistor and a diode. The diode is connected between a first source/drain region of the first transistor and a gate electrode of the first transistor such that a charge is impeded from discharging from the gate electrode to the first source/drain region. A diode layer that is part of the diode is disposed on a portion of the first source/drain region. A conductive structure that is an additional part of the diode is disposed above a portion of the gate electrode and is disposed on the diode layer. The diode can be configured as a tunnel diode. The diode layer can be produced by thermal oxidation. Only one mask is required for producing the diode. A capacitor can be disposed above the diode.

摘要： A method for producing a storage cell includes forming a polycrystalline silicon layer on a semiconductor body having at least one selection transistor disposed in a first plane. An interspace is formed between two adjacent structures of the layer and one of the adjacent structures of the layer is placed on a surface of a first silicon plug. A cell plate electrode is formed in the interspace and a trench is formed in the layer. The trench reaches as far as the first plug surface and is filled with an insulating layer. The-layer is removed. A storage capacitor having a high-epsilon or ferroelectric dielectric and a storage node electrode is formed. The capacitor is disposed in a second plane in and above the body. The insulating layer is replaced with silicon to form a second silicon plug directly connected to the first plug. The second plug is electrically connected to the storage node electrode, and the first plane is electrically connected to the second plane through the first and second plugs.
