Abstract
Spin-orbit torque magnetoresistive random access memory (SOT MRAM) devices are provided. Each of the SOT MRAM devices integrates a SOT layer and an interconnect layer at a same metal level using a topological conductor (i.e., a topological metal or a topological semimetal) as both the interconnect layer and the SOT layer. The SOT MRAM devices further include a magnetic tunnel junction (MTJ) structure contacting the SOT layer, and a contact structure contacting the MTJ structure.
