Abstract

The present invention provides a magnetic memory device. An embodiment of the present invention includes a magnetic memory cell that is switchable between two states offering electrical resistance which are detectible by a sense current though the magnetic memory cell. The device includes a field effect transistor (FET) arrangement which has a source and a drain. The source and the drain are connected by a connecting element which projects from a portion of the device and which has an electrical conductivity that varies in response to a gate voltage applied to the connecting element. The magnetic memory cell is in electrical communication with the connecting element so that at least a portion of the sense current is in use associated with a corresponding gate voltage and the FET arrangement amplifies at least a portion of the sense current.
