Heavy Metal Multilayers for Pure Electrical Switching of Perpendicularly Magnetized Magnetic Unit Via Electrical Current Without Additional Magnetic Field, Method and Applications

Case ID:
C13947

Value Proposition

·      Novel Structure: Utilizes multiple layers of heavy metals to eliminate the need for an external magnetic field, simplifying design and reducing complexity.

·      Faster Computing: Eliminates reliance on external magnetic pulses, enabling faster computing and improved operational efficiency.

·      Higher-Density Storage: Streamlined component design creates greater units’ density within the same area, maximizing storage capacity.

·      Accurate Data Writing: Eliminating external magnetic component minimizes disruption to other cells, ensuring accurate and reliable data integrity.


Unmet Need

·      Modern computing devices require efficient and high-density storage to meet growing technological demands, yet current hardware often falls short.

·      Early generation devices require an external magnetic field which negatively affects computing speed and data-writing accuracy.

·      Current devices require additional components, making them bulky, expensive, and prone to overheating.

·      There is a strong need for a compact, high-density storage device that supports rapid computing while removing the dependence on external magnetic fields.


Technology Description

·      Novel structure of multiple heavy metal layers instead of a single layer.

·      This approach eliminates the need for an external magnetic field by providing an internal source for determining the magnetism direction.

·      Removal of external components allows for a simpler structure that is easier to manufacture and can be stacked for higher-density units.


Stage of Development

·      Fully developed—the technology is patented and previously licensed.
