    摘要： A magnetic memory device includes a lower structure or an antiferromagnetic layer, a pinned layer, an information storage layer, and a free layer formed on the lower structure or the antiferromagnetic layer. In a method of operating a magnetic memory device, information from the storage information layer is read or stored after setting the magnetization of the free layer in a first magnetization direction. The information is stored when the first magnetization direction is opposite to a magnetization direction of the pinned layer, but is read when the first magnetization direction is the same as the magnetization direction of the pinned layer.
