EMBEDDED MAGNETORESISTIVE RANDOM ACCESS MEMORY TOP ELECTRODE STRUCTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17455226 titled 'EMBEDDED MAGNETORESISTIVE RANDOM ACCESS MEMORY TOP ELECTRODE STRUCTURE
Simplified Explanation
The patent application describes a method to enhance the performance of a pillar-type memory device by adding a bump of conductive material on the top electrode. Here are the key points:
- The top electrode of the pillar-type memory device is made of a thin layer of electrode material.
- A bump of conductive material is added on top of the electrode, increasing its height after the formation of the memory device.
- The bump is semi-sphere-like and slightly wider than the top electrode.
- A contact is made to connect with the bump of conductive material on the top electrode.
Potential Applications
This technology can be applied in various memory devices, such as:
- Non-volatile memory devices (e.g., flash memory)
- Resistive random-access memory (RRAM)
- Phase-change memory (PCM)
- Magnetic random-access memory (MRAM)
Problems Solved
The innovation addresses the following issues:
- Improves the performance and reliability of pillar-type memory devices.
- Enhances the electrical contact between the top electrode and other components.
- Reduces resistance and improves signal transmission in the memory device.
Benefits
The benefits of this technology include:
- Increased memory device performance and reliability.
- Improved electrical contact and signal transmission.
- Enhanced data retention and durability.
- Potential for higher memory density and storage capacity.
Original Abstract Submitted
An approach to provide a pillar-type memory device with a bump of a conductive material on a top electrode of the pillar-type memory device. The top electrode is composed of a thin layer of the top electrode material. The bump of the conductive material increases the height of the top electrode after pillar formation for the pillar-type memory device. The pillar-type memory device includes the bump of the conductive material with a semi-sphere-like bump of the conductive metal that is slightly wider than the top electrode of the pillar-type memory device. A contact connects with the bump of the conductive material on the top electrode.
