STORAGE DEVICE INCLUDING NONVOLATILE MEMORY DEVICE AND OPERATING METHOD OF STORAGE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18238262 titled 'STORAGE DEVICE INCLUDING NONVOLATILE MEMORY DEVICE AND OPERATING METHOD OF STORAGE DEVICE
Simplified Explanation
- A storage device with a nonvolatile memory device and a controller. - The controller allocates zones in the memory device based on requests from an external host device. - It manages logical addresses of data in the zones in a fixed and sequential manner. - The controller generates a page map table for each zone, containing logical and physical addresses. - When a zone is full, a read service is activated based on the zone map table. - The controller processes read requests for the zone from the external host device using the zone map table.
Potential Applications
This technology can be used in various storage devices such as solid-state drives, memory cards, and USB drives.
Problems Solved
- Efficient management of data in nonvolatile memory devices. - Improved performance in handling read requests from external host devices.
Benefits
- Enhanced data organization and access in storage devices. - Increased reliability and speed in reading data from the memory device.
Original Abstract Submitted
A storage device, including a nonvolatile memory device comprising a plurality of memory cells; and a controller configured to: allocate a plurality of zones to a storage space of the nonvolatile memory device based on a request received from an external host device, fixedly and sequentially manage logical addresses of data written in the plurality of zones, generate a first page map table corresponding to a first zone based on performing the write operation on the first zone, the first page map table comprising a logical address and a physical address of the first zone, based on the first zone being full, activate a read service, which is based on the zone map table, and based on the read service being activated, process read requests for the first zone from the external host device using the zone map table.
