Patent ID: 7315467

Claim:
A method of writing to and reading of a magnetoresistive hybrid memory cell, comprising the following steps: providing of a magnetoresistive hybrid memory cell comprising: a first stacked structure comprising a magnetic tunnel junction including first and second magnetic regions stacked in a parallel, overlying relationship separated by a layer of non-magnetic material, wherein said first magnetic region being provided with a fixed first magnetic moment vector and said second magnetic region being provided with a second free magnetic moment vector which is free to be switched between the same and opposite directions with respect to said fixed first magnetic moment vector of said first magnetic region; a second stacked structure being arranged in a lateral relationship to said first stacked structure and comprising a third magnetic region being provided with a fixed third magnetic moment vector and said second magnetic region; wherein said first and second structures being arranged in between at least two electrodes in electrical contact therewith; applying of a writing voltage pulse resulting in a writing current pulse flowing through said second magnetic region for switching of its free magnetic moment vector to electrodes on both sides of only said second structure; applying of a reading voltage pulse resulting in a reading current pulse flowing through said magnetic tunnel junction to electrodes on both sides of only said first structure.
