Abstract
Disclosed is a storage device which includes a nonvolatile memory device that includes a plurality of erase units each including a plurality of memory cells, and a memory controller. Based on an open zone request received from an external host device, the memory controller allocates a zone to at least one erase unit among the plurality of erase units and permits only a sequential write with respect to the zone. The memory controller generates a map table mapping sequential logical addresses of data written in the zone to sequential physical addresses. Based on a partial invalidation request received from the external host device, the memory controller manages data corresponding to the partial invalidation request from among the data written in the zone as invalid data while maintaining the map table.
