STORAGE CONTROLLER AND STORAGE DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17956225 titled 'STORAGE CONTROLLER AND STORAGE DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a storage device and its operating method. Here is a simplified explanation of the abstract:
- The storage device includes three non-volatile memory devices and a storage controller.
- The storage controller controls the memory devices and performs various operations.
- After a soft erase operation, the storage controller extracts a count value from the first memory device.
- Based on the count values from all three memory devices, the storage controller sets read level offsets for each memory device.
- The storage controller selects defense code parameter sets corresponding to the read level offsets.
- Finally, the storage controller transmits read commands to the memory devices based on the selected defense code parameter sets.
Potential applications of this technology:
- Data storage devices such as solid-state drives (SSDs) or memory cards.
- Embedded storage in various electronic devices like smartphones, tablets, or laptops.
- Cloud storage systems or data centers.
Problems solved by this technology:
- Ensures efficient and reliable data storage by optimizing read level offsets based on on-cell count values.
- Enhances data security by selecting defense code parameter sets based on read level offsets.
- Improves overall performance and lifespan of the storage device.
Benefits of this technology:
- Improved data storage reliability and integrity.
- Enhanced data security and protection against unauthorized access.
- Optimized performance and longevity of the storage device.
- Efficient utilization of non-volatile memory devices.
Original Abstract Submitted
A storage device and an operating method of the storage device are provided. The storage device comprises a first non-volatile memory device, a second non-volatile memory device, a third non-volatile memory device a storage controller configured to control the first non-volatile memory device, the second non-volatile memory device, and the third non-volatile memory device, control the first non-volatile memory device to extract a first on-cell count value after a first soft erase operation, set first to third read level offsets of the respective first to third non-volatile memory devices based on the respective first to third on-cell count values, select the first to third defense code parameter sets each corresponding to the respective first to third read level offsets, and transmits first to third read commands based on the selected respective first to third defense code parameter sets to the respective first to third non-volatile memory devices.
