STORAGE ABNORMALITY DETECTION DEVICE, STORAGE ABNORMALITY DETECTION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18371798 titled 'STORAGE ABNORMALITY DETECTION DEVICE, STORAGE ABNORMALITY DETECTION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM
Simplified Explanation
The storage controller in this patent application detects uncorrectable bit flips due to memory cell deterioration and prevents further writes when a predetermined number of errors have been detected for each volume written, along with confirming a total bytes written threshold has been reached.
- The innovation involves a storage controller that monitors memory cell deterioration and prevents further writes when uncorrectable errors are detected a certain number of times.
- Additionally, the controller confirms the total bytes written to ensure that a predetermined threshold has been reached before allowing further write operations.
Potential Applications
This technology could be applied in:
- Data storage systems
- Solid-state drives
- Enterprise storage solutions
Problems Solved
This technology addresses the following issues:
- Preventing data corruption due to memory cell deterioration
- Extending the lifespan of storage devices
Benefits
The benefits of this technology include:
- Improved data integrity
- Prolonged lifespan of storage devices
- Enhanced reliability of storage systems
Potential Commercial Applications
The potential commercial applications of this technology include:
- Data centers
- Cloud storage providers
- Consumer electronics manufacturers
Possible Prior Art
One possible prior art could be the use of error correction codes (ECC) in storage devices to detect and correct bit errors. However, this patent application goes beyond ECC by implementing a threshold for uncorrectable errors and total bytes written.
Unanswered Questions
How does this technology impact the overall performance of storage devices?
This article does not delve into the potential impact of this technology on the speed and efficiency of storage devices. It would be interesting to know if there are any trade-offs in performance for the increased reliability provided by the storage controller.
What are the specific criteria for determining the total bytes written threshold in this technology?
The article does not specify the exact criteria used to determine the threshold for total bytes written before preventing further write operations. Understanding the methodology behind setting this threshold could provide insights into the design and implementation of the storage controller.
Original Abstract Submitted
A storage controller performs a storage write operation, and stores being unable to write due to memory cell deterioration in cases in which bit flips uncorrectable by an ECC have been detected a predetermined number of times or more for each predetermined volume written and also writing of a TBW or greater has been confirmed.
