Abstract: Magnetic memory devices including a free magnetic layer having a three-dimensional structure, include a switching device and a magnetic tunnel junction (MTJ) cell connected thereto. The MTJ cell includes a lower magnetic layer, a tunnel barrier layer, and a free magnetic layer, which are sequentially stacked. A portion of the free magnetic layer protrudes in a direction away from an upper surface of the tunnel barrier layer.

Abstract: Oscillators and methods of operating the same, the oscillators include a pinned layer having a fixed magnetization direction, a first free layer over the pinned layer, and a second free layer over the first free layer. The oscillators are configured to generate a signal using precession of a magnetic moment of at least one of the first and second free layers.

Abstract: An information storage device includes a memory region having a magnetic track and a write/read unit, and a control circuit connected to the memory region. First and second switching devices are connected to both ends of the magnetic track, and a third switching device is connected to the write/read unit. The control circuit controls the first to third switching devices, and supplies operating current to at least one of the magnetic track and the write/read unit.
