    摘要： An operating method of a data storage device including nonvolatile memory devices includes making a victim block list for victim blocks for which a merge operation is to be performed and copying valid pages of the victim bocks to a merge block. The method also includes determining whether there is a victim block which has an erase-held valid page selectively erasing the victim blocks included in the victim block list, according to which victim blocks have an erase-held page, and updating the victim block list according to which victim blocks are erased.

    摘要： Provided herein may be a storage device and a method of operating the same. A memory controller for controlling a memory device including a plurality of memory blocks having improved read performance may include a random read workload control, unit configured to control a state of a random read workload such that the random read workload is in any one of a set state and a clear state depending on a random read count obtained by counting a number of random read requests that are inputted from an external host; and a random read processing unit configured to retrieve a physical address corresponding to a logical address of the respective random read requests depending on the state of the random read workload.
