STORAGE DEVICES AND OPERATING METHODS OF STORAGE CONTROLLERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17682084 titled 'STORAGE DEVICES AND OPERATING METHODS OF STORAGE CONTROLLERS
Simplified Explanation
The abstract describes a storage controller and method for controlling storage devices. The storage device consists of a non-volatile memory and a storage controller. The non-volatile memory has two blocks, with the first block containing memory cells that store N-bit data and the second block containing memory cells that store M-bit data. During a read reclaim operation on the first block, the storage controller identifies read hot data stored in the first block and transfers it to the second block. The storage controller selects a first word line that corresponds to a page with a number of error bits equal to or greater than a threshold value and determines the data stored in a page adjacent to the first word line as the read hot data.
- The patent describes a storage controller and method for managing storage devices.
- The storage device includes a non-volatile memory with two blocks, each containing memory cells that store different amounts of data.
- During a read reclaim operation, the storage controller identifies and transfers read hot data from the first block to the second block.
- The storage controller selects a specific page based on the number of error bits and determines the adjacent page as the read hot data.
Potential Applications
- Data storage systems
- Solid-state drives (SSDs)
- Flash memory devices
Problems Solved
- Efficient management of storage devices
- Optimization of read operations
- Minimization of data errors
Benefits
- Improved performance and reliability of storage devices
- Enhanced data management and organization
- Reduction of data errors and corruption
Original Abstract Submitted
Storage devices and an operating method of a storage controller configured to control storage devices. For example, the storage device may include a non-volatile memory and a storage controller. The non-volatile memory includes a first block and a second block, the first block including first memory cells each storing N-bit data, and the second block including second memory cells each storing M-bit data. During a read reclaim operation on the first block, the storage controller determines read hot data stored in the first block and writes the read hot data to the second block. The storage controller may select a first word line corresponding to a first page in which a number of error bits is equal to or greater than a threshold value and determine data stored in a page corresponding to a second word line adjacent to the first word line as the read hot data.
