STORAGE DEVICE AND STORAGE SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18348713 titled 'STORAGE DEVICE AND STORAGE SYSTEM
Simplified Explanation
The patent application describes a storage device with a non-volatile memory, a memory controller, and a sub controller. The memory controller communicates with a host device and controls the non-volatile memory, while the sub controller monitors the operation status of the memory controller and communicates with the host device. The sub controller performs operations such as broadcasting state information of the storage device to external devices and performing recovery operations on the memory controller when recovery information is received from external devices.
- The storage device includes a non-volatile memory, a memory controller, and a sub controller.
- The memory controller communicates with a host device through a first channel and controls the non-volatile memory.
- The sub controller communicates with the host device through a second channel and monitors the operation status of the memory controller.
- The sub controller broadcasts state information of the storage device, including the operation status, to at least one external device through the second channel.
- The sub controller performs a recovery operation on the memory controller when recovery information is received from the at least one external device through the second channel.
Potential applications of this technology:
- Data storage devices: The storage device described in the patent application can be used in various data storage devices such as solid-state drives (SSDs), USB flash drives, and memory cards.
- Embedded systems: The technology can be applied in embedded systems where reliable storage and recovery operations are crucial, such as in industrial control systems or automotive electronics.
- Cloud storage: The storage device's ability to monitor and recover from memory controller failures can enhance the reliability and availability of cloud storage systems.
Problems solved by this technology:
- Memory controller failures: The sub controller's ability to monitor the operation status of the memory controller and perform recovery operations helps in detecting and recovering from memory controller failures, ensuring the reliability of the storage device.
- Data loss prevention: By broadcasting state information and performing recovery operations, the technology helps prevent data loss in case of memory controller failures, improving the overall data integrity and reliability of the storage device.
Benefits of this technology:
- Enhanced reliability: The storage device's ability to monitor and recover from memory controller failures improves the overall reliability of the device, reducing the risk of data loss and system downtime.
- Improved data integrity: By performing recovery operations and preventing data loss, the technology ensures the integrity of stored data, providing a more reliable storage solution.
- Increased availability: The ability to broadcast state information and perform recovery operations enhances the availability of the storage device, minimizing disruptions caused by memory controller failures.
Original Abstract Submitted
Provided is a storage device including a non-volatile memory, a memory controller configured to communicate with a host device through a first channel and configured to control the non-volatile memory, and a sub controller configured to communicate with the host device through a second channel and configured to monitor an operation status of the memory controller. The sub controller is configured to perform operations including broadcasting state information of the storage device including the operation status to at least one external device through the second channel, and performing a recovery operation on the memory controller when recovery information is received from the at least one external device through the second channel.
