MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240303189 titled 'MEMORY SYSTEM
The abstract describes a patent application for a controller that can securely erase target data and read data from specific logical areas on a storage device.
- The controller responds to a command from a host to securely erase target data associated with a specific logical area identifier by storing mapping information and executing data erase operations.
- In a different mode, the controller can read data from a storage location corresponding to a specific logical area identifier based on the mapping information stored.
Potential Applications: - Data security and privacy protection in storage devices - Efficient data management in storage systems
Problems Solved: - Securely erasing sensitive data to prevent unauthorized access - Reading data from specific logical areas for retrieval and analysis
Benefits: - Enhanced data security measures - Improved data retrieval efficiency - Better control over data management processes
Commercial Applications: Title: Secure Data Erasure and Retrieval Controller for Storage Devices This technology can be used in industries such as data storage, cybersecurity, and information technology for secure data management and protection.
Questions about the technology: 1. How does the controller ensure the secure erasure of target data? The controller stores mapping information and executes data erase operations for specific logical areas to securely erase target data. 2. What are the potential implications of using this technology in data storage systems? This technology can enhance data security measures and improve data management processes in various industries.
Original Abstract Submitted
according to one embodiment, a controller, in response to receiving, from a host, a first command requesting secure erase of secure erase target data associated with a first logical area identifier, stores a copy of first mapping information that corresponds to the first logical area identifier, among mapping information that is included in a first table. the controller executes at least a data erase operation for one or more first blocks storing the secure erase target data. in a first mode, the controller, in response to receiving, from the host, a read command that specifies the first logical area identifier, reads data from a storage location corresponding to a first physical address that is mapped to the first logical area identifier in the copy of the first mapping information.
