DYNAMIC WORD LINE ALLOCATION IN MEMORY SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240249789 titled 'DYNAMIC WORD LINE ALLOCATION IN MEMORY SYSTEMS
The present disclosure involves configuring a memory sub-system controller to adaptively allocate word lines (WLs) based on reliability data of main WLs in a block of memory components. If the reliability data of one or more main WLs transgresses a threshold, the controller replaces them with dummy WLs for programming data into the block.
- Memory sub-system controller adapts word line allocation based on reliability data.
- Controller replaces main word lines with dummy word lines if reliability data transgresses a threshold.
- Data is programmed into the block using dummy word lines instead of main word lines.
Potential Applications: - Memory systems in electronic devices - Data storage systems in computers - Embedded systems in IoT devices
Problems Solved: - Efficient allocation of word lines based on reliability data - Improving data programming in memory components
Benefits: - Enhanced reliability of memory systems - Optimal performance in data storage - Improved longevity of memory components
Commercial Applications: Title: Adaptive Memory Sub-System Controller for Enhanced Data Storage This technology can be used in various electronic devices, computers, and IoT devices to improve memory system performance and reliability, leading to better user experience and longer-lasting devices.
Questions about Adaptive Memory Sub-System Controller: 1. How does the controller determine when to replace main word lines with dummy word lines? The controller replaces main word lines with dummy word lines when the reliability data associated with the main word lines transgresses a threshold, indicating potential issues with those word lines.
2. What are the potential implications of using dummy word lines for programming data in memory components? Using dummy word lines can help improve the overall reliability and performance of memory systems by ensuring that data is programmed efficiently and accurately.
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.
