A data storage device may include a storage and a controller. The storage a storage including a first region of a first physical address range and a second region of a second physical address range. The controller may generate map data including a plurality of map segments, a first segment entry and a second segment entry, and store, in the second region, the map data except for a first map segment. Each of the map segments includes a set of physical addresses corresponding to a plurality of sequential logical addresses. The first segment entry includes a first segment physical address associated with the first map segment and belonging to the first physical address range, and the second segment entry includes a second segment physical address associated with a second map segment and belonging to the second physical address range.

Data storage device and method of operating the same

A storage device may load, between a first time point at which information on candidate memory regions among a plurality of memory regions is started to be sent to an external device and a second time point at which a command requesting a map segment for a target memory region among the plurality of memory regions is received from the external device, all or a part of map segments corresponding to the candidate memory regions into a buffer.

Storage device for loading map segment and sending map segment to external device, and operating method thereof

The disclosed technology relates to an electronic device. According to the disclosed technology, a memory controller for a storage device for storing data in connection with a host in communication with the storage device includes a recommendation signal manager configured to store a plurality of recommendation signals that recommends activating a memory area of the host that stores mapping information in the memory area of the host, and a host controller configured to provide at least one of the plurality of recommendation signals to the host according to whether a number of recommendation signals provided to the host is less than a threshold value.
