Abstract

An operation method of a storage device includes receiving a request; performing an operation corresponding to the received request; generating response data corresponding to the performed operation wherein the response data includes information on the performed operation; and outputting the response data. Status information is added to and output with the response data, wherein the status information includes information on a status of the storage device.

Claims

1. An operation method of a storage device which includes a nonvolatile memory and a memory controller configured to control the nonvolatile memory, the operation method comprising:

receiving a request;

performing an operation corresponding to the received request;

generating response data corresponding to the performed operation, wherein the response data includes information on the performed operation; and

outputting the response data,

wherein status information is added to and output with the response data, wherein the status information includes information on a status of the storage device.

2. The operation method of claim 1, wherein collection of the status information is independent of the received request and the performed operation.

3. The operation method of claim 1, wherein the response data and the status information are transferred using a format of Universal Flash Storage Protocol Information Unit (UPIU).

4. The operation method of claim 3, wherein the status information is transferred using at least one field of 16^th to 31^st fields of a response UPIU.

5. The operation method of claim 3, wherein the status information is transferred using at least one field of 4^th to 7^th, 9^th, and 20^th to 31^st fields of a data out UPIU.

6. The operation method of claim 3, wherein the status information is transferred using at least one field of 20^th to 31^st fields of a ready to transfer UPIU.

7. The operation method of claim 3, wherein the status information is transferred using at least one field of 20^th to 31^st fields of a task management response UPIU.

8. The operation method of claim 3, wherein the status information is transferred using at least one field of 28^th to 31^st fields of a query response UPIU.

9. The operation method of claim 3, wherein the status information is transferred using at least one field of 16^th, 17^th, and 20^th to 27^th fields of a query response UPIU.

10. The operation method of claim 3, wherein the status information is transferred using at least one field of 16^th to 19^th and 24^th to 27^th fields of a query response UPIU.

11. The operation method of claim 3, wherein the status information is transferred using at least one field of 16^th to 22^nd and 24^th to 27^th fields of a query response UPIU.

12. The operation method of claim 3, wherein the status information is transferred using at least one field of 13^th to 27^th fields of a query response UPIU.

13. The operation method of claim 3, wherein the status information is transferred using at least one field of 12^th to 31^th fields of a NOP IN UPIU.

14. The operation method of claim 1, wherein the status information includes power-control information of the storage device.

15. The operation method of claim 14, wherein the status information further includes information on a time when the storage device enters a power-saving mode.

16. A storage device, comprising:

a nonvolatile memory; and

a memory controller configured to control the nonvolatile memory,

wherein the memory controller is further configured to collect status information including information on a status of the nonvolatile memory or the memory controller, and

wherein if an access request is received from an external device, the memory controller is configured to perform the access request, add the status information to response data including an execution result of the access request to generate first data, and output the first data to the external device.

17. A computing system, comprising:

a storage device; and

a host device configured to transmit a request to the storage device to control the storage device, write data at the storage device or read data from the storage device,

wherein the storage device is configured to collect status information including information on a status of the storage device, and

wherein the storage device is further configured to receive the request, perform the received request, add the status information to response data including an execution result of the received request to generate first data, and output the first data to the host device.

18. The computing system of claim 17, wherein the storage device is further configured to insert a first type of status information at a first location in a data format including the response data, and

wherein the host device is further configured to extract the first type of status information from the first location of the data format.

19. The computing system of claim 17, wherein the storage device is further configured to insert the status information and flag information indicating a type of the status information in a data format including the response data,

wherein the host device is further configured to extract the status information using the flag information of the status information, and

wherein the flag information is inserted at a predetermined location in the data format.

20. The computing system of claim 17, wherein the storage device is further configured to insert the status information and map information indicating a location and a type of the status information in a data format including the response data,

wherein the host device is further configured to extract the status information using the map information, and

wherein the map information is inserted at a predetermined location in the data format.
