Abstract:
1. A magnetic memory having a plurality of memory areas disposed in two-dimensional configuration of m rows and n columns, wherein m is an integer of 2 or more and n is an integer of 2 or more, each of said memory areas comprising: a magnetic material layer having: a magnetoresistive effect element including a magneto-sensitive layer of which magnetizing direction changes depending on an external magnetic field, a write wiring that provides an external magnetic field to the magneto-sensitive layer through a write current, and a read wiring electrically connected to said magnetoresistive effect element, that flows a read current to the magnetoresistive effect element; a semiconductor layer having: a first semiconductor area constituting a semiconductor write switching device that controls a conduction of the write current in said write wiring, and a second semiconductor area constituting a semiconductor read switching device that controls the conduction of the read current in the read wiring, and a wiring layer arranged between said magnetic material layer and said semiconductor layer, said wiring layer including: a first wiring electrically connected to said write wiring, and a second wiring electrically connected to a control terminal of said semiconductor write switching device, wherein said second wiring is also connected to a control terminal of said semiconductor read switching device.
