THREE-DIMENSIONAL SEMICONDUCTOR MEMORY DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18161331 titled 'THREE-DIMENSIONAL SEMICONDUCTOR MEMORY DEVICES
Simplified Explanation
The abstract describes a three-dimensional semiconductor memory device that includes multiple stack structures and vertical channel holes. A buffer pattern is placed in one of the vertical channel holes to improve the device's performance.
- The device includes a first stack structure on a substrate, a second stack structure on top of the first stack structure, and vertical channel holes that penetrate both stack structures.
- The first vertical channel hole partially exposes the substrate and the bottom surface of the second stack structure.
- The second vertical channel hole penetrates the second stack structure and exposes the first vertical channel hole.
- The bottom diameter of the second vertical channel hole is smaller than the top diameter of the first vertical channel hole.
- A buffer pattern is placed in the first vertical channel hole, adjacent to the bottom surface of the second stack structure.
Potential applications of this technology:
- Memory devices: This three-dimensional semiconductor memory device can be used in various memory applications, such as solid-state drives (SSDs) and random-access memory (RAM).
- Data storage: The device's stacked structure allows for increased storage capacity, making it suitable for applications that require large amounts of data storage, such as cloud computing and data centers.
Problems solved by this technology:
- Performance improvement: The buffer pattern placed in the vertical channel hole helps optimize the device's performance by reducing interference and improving signal transmission.
- Space efficiency: The three-dimensional structure of the device allows for more efficient use of space, enabling higher storage capacity in a smaller footprint.
Benefits of this technology:
- Increased storage capacity: The stacked structure and vertical channel holes allow for more memory cells to be packed into a smaller area, resulting in higher storage capacity.
- Improved performance: The buffer pattern helps enhance the device's performance by minimizing interference and improving signal transmission.
- Space-saving design: The three-dimensional structure of the device enables more efficient use of space, making it suitable for applications where space is limited.
