摘要

A spin-orbit torque MRAM is provided. The spin-orbit torque MRAM includes a spin Hall metal layer, a free magnetic layer disposed on the spin Hall metal layer, a barrier layer, and a pinned layer. The free magnetic layer includes a first area and a second area located on both sides thereof. The barrier layer includes a first area and a second area located on both sides thereof. The first area of the barrier layer is disposed on that of the free magnetic layer, and the second area of the barrier layer is disposed on that of the free magnetic layer. The pinned layer is disposed on the first area of the barrier layer.
