MEMORY CONTROLLER WITH IMPROVED DATA RELIABILITY AND MEMORY SYSTEM INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17895318 titled 'MEMORY CONTROLLER WITH IMPROVED DATA RELIABILITY AND MEMORY SYSTEM INCLUDING THE SAME
Simplified Explanation
The abstract describes a memory controller and memory system that improve data reliability. The memory controller operates by identifying a deteriorated region in memory blocks and taking steps to ensure data integrity.
- The memory controller copies user data from a RAID (redundant array of independent disks) to a normal region in a different block, avoiding the deteriorated region.
- Parity data from the RAID is copied to the deteriorated region of the second block, ensuring data redundancy.
- The mapping information between data in the RAID is updated and transmitted to the memory device.
Potential applications of this technology:
- Data storage systems that require high data reliability, such as enterprise storage solutions or cloud storage platforms.
- Embedded systems that rely on non-volatile memory for critical data storage, such as automotive systems or industrial control systems.
Problems solved by this technology:
- Deterioration of memory blocks can lead to data corruption or loss, which can be critical in systems that rely on accurate data storage.
- By identifying deteriorated regions and taking appropriate actions, this technology ensures data integrity and reduces the risk of data loss.
Benefits of this technology:
- Improved data reliability: By copying data to non-deteriorated regions and ensuring redundancy, the memory system provides a higher level of data integrity.
- Increased system lifespan: By effectively managing deteriorated regions, the memory system can extend the lifespan of the overall system, reducing the need for frequent memory replacements.
- Enhanced system performance: The memory controller's ability to update mapping information and optimize data storage can lead to improved system performance and faster data access.
Original Abstract Submitted
A memory controller with improved data reliability and a memory system including the same are provided, and an operating method of the memory controller includes, based on deterioration information indicating a location of a deterioration region in the plurality of blocks, with respect to data stored in a first block, copying user data of a RAID to a normal region other than the deterioration region of a second block; copying parity data of the RAID among the data stored in the first block to the deterioration region of the second block; and updating mapping information between data constituting one RAID and transmitting the mapping information to the memory device. The deterioration information includes information regarding one or more word lines at specific locations included in the deterioration region in the plurality of blocks.
