Abstract: A device controller of a storage device including a non-volatile memory peeks a command from a submission queue, and determines whether the peeked command is executable based on a status of device resources. In response to determining that the command is executable, the device controller fetches the command, allocates the device resources to the fetched command, and executes the command.

Abstract: A method of operating a storage device with a memory includes partitioning an entire area of a first namespace into at least one area based on a reference size. The partitioning is performed in response to a namespace creating request from a host that includes size information corresponding to the entire area of the first namespace. The method further includes partitioning a logical address space of the memory into a plurality of segments, allocating a first segment of the plurality of segments to a first area of the at least one area, and storing mapping information of the first area and the first segment. A size of the logical address space is greater than a size of a physical storage space of the memory identified by the host.
