STORAGE DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18200186 titled 'STORAGE DEVICE AND OPERATION METHOD THEREOF
Simplified Explanation
The abstract describes a storage device that includes a memory and a storage controller. The storage controller is responsible for controlling the memory and updating meta data. It includes a journal manager with a range table. The journal manager is designed to generate journal data related to the update of the meta data, restore the meta data by sequentially replaying each journal data, update the range table based on the journal data, and skip the replay operation for certain journal data based on the range table.
- The storage device includes a memory and a storage controller.
- The storage controller controls the memory and updates meta data.
- The storage controller includes a journal manager with a range table.
- The journal manager generates journal data for meta data updates.
- The journal manager restores the meta data by replaying the journal data.
- The range table is updated based on the journal data.
- The range table determines whether to skip replaying certain journal data.
Potential applications of this technology:
- Data storage systems
- Database management systems
- File systems
Problems solved by this technology:
- Ensures data integrity during meta data updates
- Provides a mechanism for restoring meta data in case of failures or errors
- Allows for efficient management of journal data
Benefits of this technology:
- Improved reliability and data integrity
- Faster recovery from failures or errors
- Efficient utilization of storage resources
Original Abstract Submitted
A storage device includes: a memory; and a storage controller configured to control the memory and to update meta data by controlling the memory. The storage controller includes a journal manager having a range table. The journal manager is configured to: generate a plurality of journal data associated with the update of the meta data, restore the meta data by sequentially performing a replay operation for each of the plurality of journal data, update the range table based on the plurality of journal data, and skip the replay operation for at least one of the plurality of journal data based on the range table.
