摘要:
A magnetic memory device includes a first electrode separated from a second electrode by a magnetic tunnel junction. The first electrode provides a write current path along a length of the first electrode. The magnetic tunnel junction includes a free magnetic layer having a magnetization orientation that is switchable between a high resistance state magnetization orientation and a low resistance state magnetization orientation. The free magnetic layer is spaced from the first electrode a distance of less than 10 nanometers. A current passing along the write current path generates a magnetic field. The magnetic field switches the free magnetic layer magnetization orientation between a high resistance state magnetization orientation and a low resistance state magnetization orientation.
