Unanswered Questions
How does the stepped profile of the SOT layer contribute to the overall functionality of the MRAM apparatus?
The stepped profile of the SOT layer may help to control the spin-orbit torque effect more precisely, leading to improved efficiency and reliability in data storage operations.
What are the specific materials used in the dielectric pillar to support the SOT layer and MTJ stack?
The materials chosen for the dielectric pillar must have suitable insulating properties and mechanical stability to ensure proper functioning of the MRAM apparatus.
