DYNAMIC WORD LINE ALLOCATION IN MEMORY SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18417517 titled 'DYNAMIC WORD LINE ALLOCATION IN MEMORY SYSTEMS
Simplified Explanation: The patent application describes a memory sub-system controller that adaptively allocates word lines (WLs) by replacing unreliable WLs with dummy WLs to improve data programming reliability.
- The controller accesses reliability data of main WLs in a block of memory components.
- If the reliability data of one or more main WLs transgress a threshold, the controller replaces them with dummy WLs.
- Data is then programmed into the block using the dummy WLs instead of the unreliable main WLs.
Key Features and Innovation:
- Adaptive allocation of word lines based on reliability data.
- Replacement of unreliable word lines with dummy word lines.
- Improved data programming reliability in memory systems.
Potential Applications:
- Memory systems in electronic devices.
- Data storage systems.
- Embedded systems.
Problems Solved:
- Enhancing data programming reliability.
- Addressing reliability issues in memory components.
Benefits:
- Improved overall system reliability.
- Enhanced data integrity.
- Extended lifespan of memory components.
Commercial Applications: Potential commercial applications include:
- Consumer electronics.
- Industrial automation.
- Data centers.
Prior Art: Readers can explore prior art related to memory sub-system controllers, adaptive word line allocation, and data programming reliability in memory systems.
Frequently Updated Research: Stay updated on research related to memory system reliability, adaptive memory controllers, and data programming techniques.
Questions about Memory Sub-System Controller: 1. How does the adaptive allocation of word lines improve data programming reliability?
- The adaptive allocation ensures that unreliable word lines are replaced with dummy word lines, reducing errors in data programming.
2. What are the potential applications of this technology beyond memory systems?
- This technology can be applied in various electronic devices, data storage systems, and embedded systems for improved reliability and data integrity.
Original Abstract Submitted
Aspects of the present disclosure configure a memory sub-system controller to adaptively allocate word lines (WLs). The controller accesses reliability data of a set of main WLs of a block of the set of memory components. The controller determines that one or more WLs of the set of main WLs of the block are associated with respective reliability data that transgress a threshold and, in response to determining that the one or more WLs are associated with the respective reliability data that transgress the threshold, replaces the one or more WLs of the set of main WLs of the block with one or more dummy WLs. The controller programs data into the block using the one or more dummy WLs instead of the one or more WLs of the set of main WLs of the block.
