Abstract
A storage device includes a nonvolatile memory and a controller configured to manage data, stored in the nonvolatile memory, through a plurality of namespaces. The plurality of namespaces may include a first namespace, allocated to a first logical address space, and a second namespace allocated to a second logical address space, contiguous to the first logical address space. The controller may be configured to delete the first namespace in the first logical address space in response to a request of deleting the first name space, to copy the mapping information on the second namespace from the second logical address space to the first logical address space, and to load the mapping information on the second namespace into a cache.
