DATA STORAGE DEVICE, MEMORY CONTROLLER AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18329423 titled 'DATA STORAGE DEVICE, MEMORY CONTROLLER AND METHOD OF OPERATING THE SAME
The data storage device described in the patent application includes a storage component and a memory controller. The storage is used to store data, while the memory controller generates meta-data that includes a mapping relationship between a logical address from an external device and a physical address within the storage.
- The memory controller creates a normal meta-slice with the meta-data in a first operation mode.
- A meta-page containing the normal meta-slice is stored in the storage.
- In a second operation mode, the memory controller generates a modified meta-slice as part of the normal meta-slice with a different size.
- A meta-page is then stored in the storage with the modified meta-slice and corresponding context data.
- In power-on mode, the memory controller restores the meta-data based on the context data.
Potential Applications: - Data storage systems - Memory controllers in electronic devices - Cloud storage services
Problems Solved: - Efficient mapping of logical and physical addresses - Optimized storage of meta-data - Quick restoration of meta-data in power-on mode
Benefits: - Improved data storage efficiency - Enhanced data retrieval speed - Better overall performance of storage devices
Commercial Applications: Title: "Advanced Data Storage Solutions for Enhanced Performance" This technology can be utilized in various industries such as cloud computing, data centers, and IoT devices to improve data storage efficiency and speed, leading to better overall performance and user experience.
Prior Art: Readers can explore prior art related to memory controllers, data storage systems, and meta-data management in electronic devices to gain a deeper understanding of the innovation presented in this patent application.
Frequently Updated Research: Researchers are constantly exploring new ways to optimize data storage and memory management in electronic devices, which could provide valuable insights into the future development of this technology.
Questions about the technology: 1. How does the memory controller handle the mapping relationship between logical and physical addresses? 2. What are the key differences between the first and second operation modes in terms of meta-data generation and storage?
Original Abstract Submitted
A data storage device includes a storage and a memory controller. The storage is configured to store data. The memory controller generates meta-data including a mapping relationship between a logical address used in an external device and a physical address used in the storage. The memory controller generates a normal meta-slice having a first size including the meta-data in a first operation mode. The memory controller stores a meta-page including the normal meta-slice in the storage. The memory controller generates a modified meta-slice having a second size as a part of the normal meta-slice in the second operation mode. The memory controller stores a meta-page including the modified meta-slice and context data corresponding to size information of the modified meta-slice in the storage. The memory controller restores the meta-data based on the context data in a power-on mode.
