Abstract
A memory device and a memory circuit is provided. The memory device includes a spin-orbit torque (SOT) layer, a magnetic tunnel junction (MTJ), a read word line, a selector and a write word line. The MTJ stands on the SOT layer. The read word line is electrically connected to the MTJ. The write word line is connected to the SOT layer through the selector. The write word line is electrically connected to the SOT layer when the selector is turned on, and the write word line is electrically isolated from the SOT layer when the selector is in an off state.
