Abstract: A storage device includes a non-volatile memory including a plurality of memory blocks. The storage device performs an alignment operation in response to receipt of an align command. The alignment operation converts a received logical address of a logical segment into a physical address and allocates the physical address to a physical block address corresponding to a free block. The storage device is further configured to performs a garbage collection in units of the physical block address that indicates one memory block.

Abstract: In a method of operating a storage device, the storage device includes a plurality of memory blocks. A data write request and target data to be written are received. Using a data classifier, such as a neural network model, the target data is assigned to a stream selected from a plurality of streams based on a data property of the target data. The target data is written into a memory block assigned to a stream selected for assignment of the target data, such that target data that has been assigned to a stream are written into the one or more memory blocks assigned to the stream.

Abstract: In a data management method for a storage device, the storage device includes a nonvolatile memory device including a plurality of memory blocks. A TRIM-after-COPY command is received from an external host such that a data compaction operation is performed on a first storage region. Valid data stored in the first storage region are internally copied into a second storage region based on the TRIM-after-COPY command. A TRIM operation is performed based on the TRIM-after-COPY command to update a logical-to-physical address mapping table and a valid page bitmap.

Abstract: Victim segments to be returned to a free area in a segment cleaning process from a plurality of segments included in each segment group are selected by using a method corresponding to the segment group. A host comprises an interface relaying data exchange with a storage device; and a file system module performing a segment cleaning process by selecting victim segment from a plurality of segments stored in the storage device, discovering live blocks in each of the victim segments, writing back the discovered live blocks to the storage device through the interface, and returning the victim segments to a free area. The file system module calculates victim points for all segments included in a first segment group using a first victim point calculation formula, calculates victim points for all segments included in a second segment group using a second victim point calculation formula, and selects the victim segments based on the victim points.
