STORAGE DEVICE PERFORMING SELF-DIAGNOSIS AND STORAGE SYSTEM INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17987447 titled 'STORAGE DEVICE PERFORMING SELF-DIAGNOSIS AND STORAGE SYSTEM INCLUDING THE SAME
Simplified Explanation
The abstract describes a storage device that connects to a RAID controller and includes multiple non-volatile memories. A memory controller controls these memories to store data based on a RAID configuration signal received from the RAID controller. The memory controller also performs self-diagnosis on the memories to identify any uncorrectable errors when the RAID configuration signal is deactivated.
- The storage device is designed to be connected to a RAID controller.
- It includes multiple non-volatile memories.
- A memory controller manages these memories to store data distributed by the RAID controller.
- The memory controller relies on a RAID configuration signal received from the RAID controller.
- When the RAID configuration signal is deactivated, the memory controller performs self-diagnosis on the memories.
- The purpose of the self-diagnosis is to identify any uncorrectable errors in the memories.
Potential Applications
- Data storage systems utilizing RAID technology.
- Redundant storage systems requiring error detection and correction.
Problems Solved
- Ensures data integrity by detecting uncorrectable errors in non-volatile memories.
- Provides a mechanism for self-diagnosis of storage device components.
- Enables proactive identification and replacement of faulty memories.
Benefits
- Improved reliability and data integrity in RAID-based storage systems.
- Early detection of memory errors allows for timely replacement, reducing the risk of data loss.
- Simplifies maintenance and troubleshooting by automatically diagnosing memory issues.
Original Abstract Submitted
A storage device configured to be connected to a redundant array of inexpensive disk (RAID) controller includes a plurality of non-volatile memories. A memory controller is configured to control the plurality of non-volatile memories to store data distributed by the RAID controller based on a RAID configuration signal received from the RAID controller. The memory controller is configured to perform self-diagnosis on the plurality of non-volatile memories to determine whether at least one of the plurality of non-volatile memories has an uncorrectable error when a RAID configuration signal is deactivated.
