Abstract: A memory device may comprise a substrate defining a main plane; a plurality of memory cells each comprising a SOT current layer disposed in the main plane of the substrate and a magnetic tunnel junction residing on the SOT current layer; and a bit line and a source line to flow a write current in a write path including the SOT current layer of a selected memory cell. The source line comprises a conductive magnetic material providing a magnetic bias field extending to the magnetic tunnel junction of the selected memory cell for assisting the switching of the cell state when the write current is flowing.

Abstract: A method for standardizing computer system action, including: intercepting invoking command; obtaining data structure of the intercepted invoking command after intercepting the invoking command; determining the sponsor of the intercepted invoking command based on the data structure of the obtained and intercepted invoking command, and determining operation method and operation object of the intercepted invoking command; matching the sponsor, the operation method and the operation object of the intercepted invoking command with rules of standardizing computer system action, judging whether to allow executing the intercepted invoking command. The present disclosure determines the sponsor of the intercepted invoking command according to the data structure of the invoking command, and can monitor comprehensively computer system. If only the sponsor is spiteful, the disclosure does not all allow executing the intercepted invoking command, thus detecting lawless operation comprehensively and effectively.
