Abstract:
A memory element ( 10 ) includes a free magnetization layer ( 12 ) in a film form, a nonmagnetic layer ( 13 ), and a fixed magnetization layer ( 14 ), the nonmagnetic layer ( 13 ) and the fixed magnetization layer ( 14 ) being stacked on the free magnetization layer ( 12 ). The free magnetization layer ( 12 ) stores a single bit of data “0” or “1” according to a magnetization direction and rewrites the data by reversing the magnetization direction. An antiferromagnet that exhibits the anomalous Hall effect and has a reversible magnetization direction is used for the free magnetization layer ( 12 ). The reversal of the magnetization direction of the free magnetization layer ( 12 ) is performed using the fixed magnetization layer ( 14 ) by the spin-transfer torque technique. To read data, a reading current (If) is caused to flow in one direction, and a Hall voltage generated in the free magnetization layer ( 12 ) by the anomalous Hall effect is extracted from the free magnetization layer ( 12 ). The polarity of the Hall voltage is reversed in accordance with the magnetization direction of the free magnetization layer ( 12 ).

Claim (Index 9):
The memory element according to  claim 2 , wherein\n the magnetization reversing unit includes a word line and a bit line, an electric current is caused to flow in one direction through the word line, and a direction of an electric current is changed depending on data to be written in the bit line, and the free magnetization layer is disposed at an intersection of the word line and the bit line, and a magnetization direction of the antiferromagnet is reversed in accordance with the direction of the electric current flowing through the bit line.
