CRITICAL DATA MANAGEMENT WITHIN A MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18443011 titled 'CRITICAL DATA MANAGEMENT WITHIN A MEMORY SYSTEM
Simplified Explanation
The patent application describes methods, systems, and devices for managing critical data within a memory system. It involves avoiding writing critical data to weak word lines in the memory system.
- The memory system determines which data is critical and which word lines are weak based on error rates.
- Critical data is not written to memory cells with weak word lines, instead non-critical or dummy data is written.
- Critical data is reserved for memory cells with non-weak word lines.
Key Features and Innovation
- Management of critical data within a memory system.
- Avoidance of writing critical data to weak word lines.
- Determination of critical data and weak word lines based on error rates.
- Writing non-critical or dummy data to weak word lines.
- Reserving critical data for memory cells with non-weak word lines.
Potential Applications
This technology can be applied in various memory systems where critical data management is crucial, such as in media management operations or host write operations.
Problems Solved
This technology addresses the issue of potential data corruption by avoiding writing critical data to memory cells with weak word lines, thus improving data reliability and integrity.
Benefits
- Enhanced data reliability and integrity.
- Improved management of critical data within memory systems.
- Reduced risk of data corruption.
Commercial Applications
- Data storage systems
- Cloud computing infrastructure
- Embedded systems

Original Abstract Submitted
Methods, systems, and devices for critical data management within a memory system are described. A memory system may avoid writing critical data to weak word lines. For example, as part of a media management operation or a host write operation (among other examples), the memory system may determine which data is critical data and may determine which word lines are weak word lines, which may refer to word lines having bit error rates that satisfy a threshold. The memory system may refrain from writing critical data to memory cells coupled with weak word lines, and may instead write non-critical or dummy data to the weak word lines. The memory system may reserve the writing of critical data to memory cells coupled with non-weak word lines, which may refer to word lines having bit error rates that fail to satisfy the threshold.
