Patent ID: 7345912

Claim:
A magnetic memory comprising: a plurality of magnetic memory cells, each of the plurality of magnetic memory cells including a magnetic element and a selection device connected with the magnetic element, the magnetic element being programmed by a first write current driven through the magnetic element in a first direction and a second write current driven through the magnetic element in a second direction; a plurality of local word lines connected with the selection device of a first portion of the plurality of magnetic memory cells, each of the local word lines having a first resistivity; a plurality of global word lines, each of the plurality of global word lines corresponding to a portion of the plurality of local word lines and having a second resistivity lower than the first resistivity; a plurality of bit lines connected with the magnetic element of each of the plurality of magnetic memory cells; and a plurality of source lines connected with the selection device of each of the plurality of magnetic storage cells, each of the plurality of source lines corresponding to a second portion of the plurality of magnetic memory cells and carrying the first write current and the second write current, the second portion of the plurality of magnetic memory cells including more than a single magnetic memory cell.
