Original Abstract Submitted
A storage device, including: a nonvolatile memory device comprising a plurality of memory cells; and a controller configured to perform a write operation on at least one write unit included in the plurality of memory cells, and to perform an erase operation on at least one erase unit included in the plurality of memory cells, wherein the controller is further configured to: allocate a plurality of zones to a storage space of the nonvolatile memory device based on a request received from an external host device, select two or more erase units from among a plurality of erase units included in the plurality of memory cells to be allocated to each zone of the plurality of zones, fixedly and sequentially manage logical addresses of data to be written in the plurality of zones, and generate at least two map tables for the each zone
