摘要： Disclosed is a method for operating a logic device (10), according to which at least one output variable O = F (IA, IB) is formed from input variables (IA, IB) with an operator function F of the magnetic logic device (10) by means of at least one logic operation, the logic device (10) being set to a start mode prior to the operation with the aid of a specific operator control signal (SET) so as to execute the operator function F. Said operator control signal is selected among a group of control signals, by means of which different nonvolatile start modes that are characteristic of different logic functions can be specifically set. Also disclosed is a magnetic logic device (10) which is set up so as to implement the inventive method.

摘要： The present invention relates to a device (9) for performing a "logic function", comprising a magnetic structure including: at least a first magnetoresistive stack (MTJ1) that includes a first ferromagnetic layer and a second ferromagnetic layer that are separated by a non-ferromagnetic interlayer, the hard ferromagnetic layer being trapped in a fixed magnetic state serving as reference; and at least a first (19) and a second (18) current line belonging to a first (N3) and a second (N2) metallization level respectively, each of said two lines generating a magnetic field in the vicinity of the first stack when an electrical current passes therethrough. The first and second lines (19, 18) are placed at different distances from the second layer, said distances being determined by the "logic function".

摘要： The invention relates to a reconfigurable magnetic logic circuit arrangement having at least two magnetoresistive elements comprising at least two respective magnetic layers, which are each separated from one another by an intermediate layer, wherein one of the magnetic layers, as a reference layer, does not considerably change its magnetization under the influence of external magnetic fields and the other magnetic layer, as a free layer, changes in a manner which can be detected, and at least one conductor for signal connections, which, when current flows through it, can be used to generate a first magnetic field which changes over the magnetization of the free layers, as well as a device for generating, as required, a second variable magnetic field which likewise influences the magnetoresistive elements. In this case, two magnetoresistive elements of this type are arranged adjacent to one another, wherein the magnetization of the two reference layers is oriented in opposite directions by means of preset unidirectional anisotropy and the magnetoresistive elements are connected to one another in such a manner that, as a result of the first and second magnetic fields acting on the magnetoresistive elements, the switching behaviour of all fundamental logic functions, in particular the AND, OR, NAND, NOR, XOR or XNOR functions, can be induced on the basis of the resultant changes in the orientation of the magnetization of the free layers and thus the resistance of the magnetoresistive elements in the logic circuit arrangement.

摘要： The circuit part (B) contains at least two layer elements (E1-E4), which respectively exhibit an increased magnetoresistive XMR effect, for example, a TMR effect and comprise a thin series of layers with: a magnetically soft detection layer; a magnetically harder reference layer, and; a decoupling intermediate layer located therebetween. Both layer elements should generate output signals whose signs are inverted with regard to one another. To this end, the setting of the different signs of the magnetoresistive effect of both layer elements (E1, E2 or E3, E4) is predetermined by means of a varied layer structure of at least the detection layers or intermediate layers thereof.
