REDUCING BIT ERROR RATE IN MEMORY DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18219023 titled 'REDUCING BIT ERROR RATE IN MEMORY DEVICES
Simplified Explanation
The abstract describes a processing device in a memory sub-system that performs media scan and management operations on memory pages based on data state metrics.
- Processing device in memory sub-system performs first media scan operation on memory pages addressable by ordinary wordline
- Each memory page is contained by a management unit
- If data state metric of a memory page satisfies specified condition, first media management operation is performed on the management unit
- Processing device also performs second media scan operation on memory pages addressable by mandatory wordline
- If data state metric of a memory page satisfies specified condition, second media management operation is performed on the management unit
---
- Potential Applications
- Memory management in computer systems
- Data storage devices
- Error detection and correction in memory systems
- Problems Solved
- Efficient management of memory pages based on data state metrics
- Improved reliability and performance of memory sub-systems
- Benefits
- Enhanced data integrity
- Optimized memory utilization
- Increased system stability and reliability
Original Abstract Submitted
A processing device in a memory sub-system performs a first media scan operation with respect to a plurality of memory pages addressable by the ordinary wordline, wherein each page of the plurality of memory pages is contained by a respective management unit, and responsive to determining that a value of a data state metric of a memory page of the plurality of memory page addressable by the ordinary wordline satisfies a specified condition, performs a first media management operation with respect to a management unit containing the memory page. The processing device further performs a second media scan operation with respect to a plurality of memory pages addressable by the mandatory wordline, wherein each page of the plurality of memory pages is contained by the respective management unit, and responsive to determining that a value of the data state metric of a memory page of the plurality of memory page addressable by the mandatory wordline satisfies the specified condition, performs a second media management operation with respect to the management unit containing the memory page.
