    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.

    Abstract: A storage device and an operating method of the same are disclosed. The storage device includes a memory controller and a non-volatile memory, wherein the memory controller is configured to calculate a number of zones, which are spaces allocated to logical addresses, based on a cell area size of first storage areas of the non-volatile memory, and provide the number of zones to a host, is configured to generate multiple zones of a number within the calculated number of zones, and to map a logical address of each zone to a physical address of at least one of the first storage areas, and is configured to, in response to a first write request from the host, write data included in the first write request into first storage areas corresponding to a zone indicated by the first write request.

    Abstract: Provided are a storage device configured to perform high-speed link startup and a storage system including the storage device. The storage system performs data communication through a connected transmission lane and a connected reception lane from among a plurality of lanes between a host and the storage device. The host transmits an activate period of the connected transmission lane, which is less than a first time period, to the connected reception lane, and the storage device receives the activate period of the connected reception lane, which is less than the first time period. The host and the storage device perform link startup in a high-speed mode through the connected transmission lane and the connected reception lane, based on the activate period being less than the first time period.
