摘要： A magnetoresistive memory element including a trapped magnetic region and a free magnetic region separated by a barrier layer. The free magnetic region comprises a stacking of at least two antiferromagnetically-coupled ferromagnetic layers, a layer magnetic moment vector being associated with each layer, the resulting magnetic moment vector, equal to the sum of the layer magnetic moment vectors, having an amplitude smaller than at least 40% of the amplitude of the layer magnetic moment vector of maximum amplitude. The anisotropy field and/or the demagnetizing field tensor is not identical for the at least two ferromagnetic layers, whereby the angular deviations of the layer magnetic moment vectors are different at the time of the application of an external magnetic field, which enables at least two methods for directly writing into the memory element, as well as its initialization.

摘要： A method of operating a magnetoresistive device is described. The device comprises a ferromagnetic region configured to exhibit magnetic anisotropy and to allow magnetisation thereof to be switched between at least first and second orientations and a gate capacitively coupled to the ferromagnetic region. The method comprises applying an electric field pulse to the ferromagnetic region so as to cause orientation of magnetic anisotropy to change for switching magnetisation between the first and second orientations.

摘要： A magnetic memory device comprises a magnetic tunnel junction (MTJ) connecting to a bit line to a sense line through an isolation transistor. The MTJ includes a ferromagnetic layer having a magnetic hard axis. An assist current line overlies the bit line and is insulated from the bit line. The MTJ is switchable between a first, relatively high resistance state and a second, relatively low resistance state. The assist current line applies a magnetic field along the magnetic hard axis in the ferromagnetic layer, independently of current flow through the MTJ for assisting switching of the MTJ between the first and second states.

摘要： An architecture and method are provided for reading and writing, in parallel or in series, an electronic memory component based on a two-dimensional matrix of two-terminal binary memory unit cells built into a crossbar architecture. The component includes a logical column-selector located outside the matrix and activating at least one column, one or more cells of which are subjected to read or write processing. Also provided is a component and method with the reading of the status of the cells by differential detection on from two cells of two different rows, either between a storage column and a constant reference column, or between two rows or two storage columns. A component is also provided in which specific selection structure is exclusively dedicated to read operations, and/or in which complementary cells in two complementary columns connected together are encoded in a single atomic operation by means of a single write current.
