Abstract:
1. A magnetic memory, comprising: bit lines; word lines; and memory cells, each of said memory cells being installed at intersections of the bit lines and the word lines, wherein each of said memory cells comprises a magnetoresistive layer, a highly polarized spin injection layer, a barrier layer inserted between said highly polarized spin injection layer and said magnetoresistive layer, a first terminal formed on at least one end of said highly polarized spin injection layer, a second terminal formed on at least one end of said magnetoresistive layer, a third terminal layer formed on a first surface of said magnetoresistive layer surface, the first surface being opposite to a second surface of said magnetoresistive layer, the second surface contacting said barrier layer, and a means for adjusting a bias voltage to be applied to said highly polarized spin injection layer through said first terminal, and wherein said magnetoresistive layer comprises a free layer, a pinned layer, an insulation layer formed between said free layer and said pinned layer, and a terminal for a current provided on an end of said free layer or said pinned layer.
