Magnetic random access memory and operation method of the same
Abstract:
A magnetic random access memory of the present invention includes: a plurality of first wirings and a plurality of second wirings extending in a first direction; a plurality of third wirings and a plurality of fourth wirings extending in a second direction; and a plurality of memory cells provided at intersections of the plurality of first wirings and the plurality of third wirings, respectively. Each of the plurality of memory cells includes: a first transistor and a second transistor connected in series between one of the plurality of first wirings and one of the plurality of second wirings and controlled in response to a signal on one of the plurality of third wirings, a first magnetic resistance element having one end connected to a write wiring through which the first transistor and the second transistor are connected, and the other end grounded; and a second magnetic resistance element having one end connected to the write wiring, and the other end connected to the fourth wiring.
