STORAGE DEVICE SUPPORTING TRIM OPERATION AND STORAGE SYSTEM INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240201867 titled 'STORAGE DEVICE SUPPORTING TRIM OPERATION AND STORAGE SYSTEM INCLUDING THE SAME
The abstract describes a storage device that includes a memory device and a solid-state drive used as a cache memory for the memory device. The solid-state drive consists of a storage unit with nonvolatile memory cells, a memory controller, and a data management unit that organizes data based on access time.
- The solid-state drive manages data stored in the storage unit in order of less recent access time.
- The data management unit identifies cold data based on access time and sends an internal trim command to the memory controller for the cold data.
- The memory controller performs an internal trim operation on the cold data when the valid data ratio of the storage unit exceeds a reference valid ratio.
Potential Applications: - This technology can be used in storage devices for computers, servers, and other electronic devices. - It can improve the efficiency and performance of data storage systems by optimizing data management.
Problems Solved: - Efficient organization and management of data based on access time. - Optimization of storage space by identifying and trimming cold data.
Benefits: - Enhanced performance and speed of data access. - Improved storage efficiency and utilization. - Extended lifespan of storage devices.
Commercial Applications: Title: Enhanced Data Management Technology for Storage Devices This technology can be commercialized for use in data centers, cloud storage services, and consumer electronics to enhance data storage efficiency and performance. It can cater to a wide range of industries that rely on efficient data management systems.
Questions about the technology: 1. How does the data management unit determine cold data in the storage unit? The data management unit identifies cold data based on access time and sends an internal trim command to the memory controller for the cold data.
2. What is the significance of the memory controller performing an internal trim operation on the cold data? The internal trim operation helps optimize storage space by removing less frequently accessed data, improving overall system performance.
Original Abstract Submitted
a storage device includes a memory device and a solid state drive used as a cache memory for the memory device. the solid state drive includes a storage unit including a plurality of nonvolatile memory cells, a memory controller configured to control the storage unit, and a data management unit configured to manage pieces of data, stored in the storage unit, in order of less recent access time. the data management unit may set at least one of the pieces of data, stored in the storage unit, as cold data based on a data access point in time, and may send an internal trim command for the cold data to the memory controller when a valid data ratio of the storage unit is higher than a reference valid ratio. the memory controller may perform an internal trim operation on the cold data.
