Data storage device, data processing system, and operating method of data storage device
A data storage device may include a controller configured to generate an ID based on a name and a version of an application transmitted from a host device together with a logic address, and generate an L2P map list for each application based on the ID; and a nonvolatile memory apparatus including a plurality of map blocks configured to store map data for each ID.
1. A data processing system comprising:
a host device configured to transmit a name and a version of an application to a data storage device together with a logical address; and
the data storage device configured to generate an identification (ID) based on the name and version of the application transmitted from the host device, generate a logical address to physical address (L2P) map list for each application based on the ID, and store the L2P map list in a corresponding map block.
2. The data processing system according to claim 1 , wherein the data storage device applies a hash function to the name and version of the application to generate the ID.
3. The data processing system according to claim 1 , wherein, when a foreground application is changed, the host device transmits a name and a version of the foreground application to the data storage device, and
the data storage device returns map data for the foreground application based on the L2P map list, to the host device.
4. The data processing system according to claim 3 , wherein the data storage device comprises:
a memory configured to store the L2P map list that matches the ID;
a plurality of map blocks configured to store map data for each ID; and
a processor electrically connected to the host device and configured to control an operation of the data storage device,
wherein the processor generates and manages the ID by applying a hash function to the name and version of the application, and searches for and returns an ID that matches the name and version of the foreground application.
5. The data processing system according to claim 4 , wherein, when the map data for each ID is stored across two or more map blocks, the map data for each ID includes a physical address link of a next map block.
6. The data processing system according to claim 3 , wherein the map data for the foreground application is L2P map data including a logical address and a physical address of the foreground application.
7. The data processing system according to claim 3 , wherein the host device stores the map data for the foreground application transmitted from the data storage device, in a host memory, and transmits, when map data corresponding to a logic address to access is stored in the host memory, the map data to the data storage device along with a read command.
8. The data processing system according to claim 1 , wherein the host device transmits the name and version of the application, and the logical address to the data storage device when transmitting a read command to the data storage device.
9. A data storage device comprising:
a controller configured to generate an ID based on a name and a version of an application transmitted from a host device together with a logic address, and generate an L2P map list for each application based on the ID; and
a nonvolatile memory apparatus including a plurality of map blocks configured to store map data for each ID.
10. The data storage device according to claim 9 , wherein the data storage device applies a hash function to the name and version of the application to generate the ID.
11. The data storage device according to claim 9 , wherein, the controller, when a foreground application is changed, receives a name and a version of the foreground application from the host device, and searches for and returns corresponding map data based on the ID.
12. The data storage device according to claim 11 , wherein the controller comprises:
a memory configured to store the L2P map list that matches the ID; and
a processor electrically connected to the host device and configured to control an operation of the data storage device,
wherein the processor generates and manages the ID by applying a hash function to the name and version of the application, and searches for and returns an ID that matches the name and version of the foreground application.
13. The data storage device according to claim 11 , wherein, when the map data for each ID is stored across two or more map blocks, the map data for each ID includes a physical address link of a next map block.
14. The data storage device according to claim 11 , wherein the returned map data is L2P map data including a logical address and a physical address of the foreground application.
15. An operating method of a data storage device, comprising:
generating an ID based on application information transmitted from a host device;
generating an L2P map list for each application based on the ID; and
storing map data for each ID.
16. The operating method according to claim 15 , wherein the generating the ID comprises:
receiving a name and a version of the application from the host device; and
generating the ID by applying a hash function to the name and version of the application.
17. The operating method according to claim 15 , wherein, in the storing of the map data for each ID, when the map data for each ID is stored across at least two or more blocks, the map data for each ID includes a physical address link of a next map block.
18. The operating method according to claim 17 , wherein receiving the information on the foreground application from the host device indicates that a name and a version of the foreground application are received from the host device, and
wherein the step of searching for and returning the map data comprises:
a step of searching for an ID that matches the name and the version of the foreground application; and
a step of searching for and returning map data corresponding to the name and the version of the application based on the searched ID.
19. The operating method according to claim 15 , further comprising:
searching for, when information on a foreground application is received from the host device, an ID that matches the information on the foreground application; and
returning map data corresponding to the information of the foreground application based on the searched ID.
20. The operating method according to claim 19 , wherein the returned map data is L2P map data including a logical address and a physical address of the foreground application.
