US Patent 7349235 Non-volatile memory device

A non-volatile memory device according to one embodiment includes a plurality of memory cells each comprising a magneto resistive element and a selection transistor, where the memory cells are arranged into a two dimensional array. A first interconnect line extends in a first direction of the memory array and functions as a gate electrode of a selection transistor included in each memory cell. A second interconnect line extends in the first direction of the memory array. A third interconnect line extends in a second direction. The magneto resistive element of at least some of the memory cells is sandwiched between the second and third interconnect lines.
