Abstract: An operating method of a memory controller may include receiving a state analysis request of a memory from a host, determining a fragment state of the memory, determining a lifespan situation of the memory, generating an analysis result indicating whether a garbage collection is restricted, on the basis of the fragment state and the lifespan situation, and providing the analysis results to the host.

Abstract: A storage device includes a nonvolatile memory device that includes a plurality of memory blocks, and a controller that uses some memory blocks of the plurality of memory blocks as a buffer area. Memory blocks storing invalid data from among the some memory blocks are invalid memory blocks, and the controller identifies memory blocks, of which an elapsed time after erase is greater than a reuse time, from among the invalid memory blocks as an available buffer size, and provides the available buffer size to an external host device.

Abstract: An operation method of a universal flash storage (UFS) host configured to control a UFS device includes configuring a turbo write buffer of the UFS device; sending a first query request UFS protocol information unit (UPIU) including reconfiguration information about the turbo write buffer to the UFS device, during driving the UFS device; and receiving a first response UPIU associated with the first query request UPIU from the UFS device, wherein, the first query request UPIU is a request that causes a size of the turbo write buffer of the UFS device to be changed from a first size to a second size different from the first size.

Abstract: A storage device includes: a buffer to receive first data and second data from outside, and store the first data and the second data on a first page; a non-volatile memory to store the first data and the second data in a first block; and a controller to perform a program operation that programs the first and second data in free blocks different from each other through a garbage collection. The first data may include a first stream class number identifying characteristics of the first data, and the second data may include a second stream class number identifying characteristics of the second data and is different from the first stream class number. The controller may transmit information of the program operation to the outside before performing the program operation. The controller may perform the program operation when receiving a program execution permission command from the outside.
