    摘要: A memory device is provided. The memory device includes a memory layer and a fixed-magnetization layer. The memory layer retains information based on a magnetization state of a magnetic material. The fixed-magnetization layer is formed on the memory layer through an intermediate layer made of an insulating material. The information is recorded on the memory layer with a change in a magnetization direction of the memory layer caused by injecting a spin-polarized electron in a stacked direction. A level of effective demagnetizing field, which is received by the memory layer, is smaller than a saturation-magnetization level of magnetization of the memory layer.

    摘要: A memory including a memory element having a memory layer that retains information based on a magnetization state of a magnetic material, and a conductor electrically connected to the memory element is provided. In the memory, a magnetization pinned layer is provided for the memory layer through an intermediate layer, the intermediate layer is formed of an insulator, and spin-polarized electrons are injected in a stacking direction to invert a magnetization direction of the memory layer, so that information is recorded in the memory layer. The magnetic material is also provided for the conductor, so that a magnetic field with current flowing in the conductor is enhanced and a leakage magnetic field is applied to the memory layer to cause a deviation of the magnetization direction of the memory layer. Current in the stacking direction flows into the memory element through the conductor, so that spin-polarized electrons are injected.
