Abstract
A data storage device includes a storage, and a controller configured to control data exchange with the storage in response to a request of a host device; generate a name space, which is a logical area and includes one or more sub-spaces each serving as a physical area of the storage, in response to the request of the host device; and manage mapping information between the name space and the sub-spaces, wherein each sub-space constituting the name space is selected to have a physically continuous or discontinuous address.
Claims20
A data storage device comprising:
- a storage;
- and
- a controller configured to:
- control data exchange with the storage in response to a request of a host device;
- generate a name space, which is a logical area and includes one or more sub-spaces each serving as a physical area of the storage, in response to the request of the host device;
- and
- manage mapping information between the name space and the sub-spaces,
- wherein each sub-space constituting the name space is selected to have a physically continuous or discontinuous address.
An operation method of a data storage device including a storage and a controller configured to control data exchange with the storage, the method comprising:
- generating, by the controller, a name space, which is a logical area and includes one or more sub-spaces each serving as a physical area of the storage, in response to a request of the host device;
- and
- updating, by the controller, mapping information between the name space and the sub-spaces,
- wherein each sub-space constituting the name space is selected to have a physically continuous or discontinuous address.
A memory system comprising:
- a memory device including a plurality of storage segments each represented by a physical address;
- and
- a controller configured to:
- assign one or more among the storage segments for a name space addressable by an external device;
- release one or more among the storage segments assigned for the name space;
- update relationship between one or more among the assigned and released storage segments and the name space within first and second tables;
- and
- control, through the first and second tables, access to the assigned storage segments in response to an access request provided along with a logical address of the name space from the external device.
