MAGNETIC TUNNEL JUNCTION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240130243 titled 'MAGNETIC TUNNEL JUNCTION DEVICE
Simplified Explanation
The present invention provides a magnetic tunnel junction (MTJ) structure with a unique design featuring multiple sub free layers in the free layer.
- The MTJ structure includes a tunnel barrier layer on a reference layer and a free layer on the tunnel barrier layer.
- The free layer consists of multiple ferromagnetic strips placed parallel to each other on the tunnel barrier layer.
- The multiple ferromagnetic strips are connected to electrodes at their respective ends.
- The design of the MTJ structure allows for improved performance and efficiency in magnetic tunnel junction devices.
Potential Applications
The MTJ structure can be used in:
- Magnetic random-access memory (MRAM) devices
- Magnetic sensors
- Spintronic devices
Problems Solved
- Improved performance and efficiency in magnetic tunnel junction devices
- Enhanced data storage capabilities in MRAM devices
- Increased sensitivity and accuracy in magnetic sensors
Benefits
- Higher data storage density
- Faster data access speeds
- Lower power consumption
- Enhanced device reliability
Potential Commercial Applications
"Enhancing Magnetic Tunnel Junction Devices with Multiple Sub Free Layers"
Possible Prior Art
There have been previous designs of magnetic tunnel junction structures with different configurations of the free layer, but none specifically with multiple sub free layers as described in this invention.
Unanswered Questions
