         2 . The data storage device of  claim 1 , wherein each of the attributes is generated as a program code and comprised as a part of the firmware. 
     
     
         3 . The data storage device of  claim 1 , wherein the firmware comprises at least one subprogram, and the firmware execution code branch information includes information defining an execution sequence of the at least one subprogram. 
     
     
         4 . The data storage device of  claim 3 , wherein each of the attributes is generated as a program code and linked with the at least one subprogram to be stored as the firmware. 
     
     
         5 . The data storage device of  claim 1 , wherein the controller is configured to set a register according to information set for each of the attributes and execute the firmware according to the firmware execution code branch information. 
     
     
         6 . An operation method of a data storage device comprising a storage and a controller, the operation method comprising:
 storing, to a set region of the storage, flag information on attributes, each attribute corresponding to a revision version, and firmware comprising register setting information and firmware execution code branch information for each attribute; and   reading, by the controller, the flag information and the firmware from the storage to execute the firmware according to the flag information.   
     
     
         7 . The operation method of  claim 6 , wherein each of the attributes is generated as a program code and comprised as a part of the firmware. 
     
     
         8 . The operation method of  claim 6 , wherein the firmware comprises at least one subprogram, and the firmware execution code branch information includes information defining an execution sequence of the at least one subprogram. 
     
     
         9 . The operation method of  claim 8 , wherein each of the attributes is generated as a program code and linked with the at least one subprogram to be stored as the firmware. 
     
     
         10 . The operation method of  claim 6 , further comprising:
 setting, by the controller, a register according to information set for each of the attributes; and   executing, by the controller, the firmware according to the firmware execution code branch information.   
     
     
         11 . A firmware providing server, which is configured to provide firmware to a data storage device, the firmware providing server comprising:
 a flag setter configured to determine an attribute of flag information corresponding to a revision version of the data storage device, the flag information including attributes; and   a firmware generator configured to generate firmware necessary to operate the data storage device, change the firmware so as to reflect register setting information and firmware execution code branch information according to the revision version of the data storage device, the register setting information and firmware execution code branch information being set for each attribute, and provide the changed firmware and the determined attribute of the flag information to the data storage device.   
     
     
         12 . The firmware providing server of  claim 11 , further comprising a characteristic code generator configured to generate the determined attribute of the flag information as a program code. 
     
     
         13 . The firmware providing server of  claim 12 , wherein the firmware generator is configured to change the firmware so as to comprise the characteristic code. 
     
     
         14 . The firmware providing server of  claim 13 , wherein the firmware generator is configured to provide the firmware comprising the characteristic code to the data storage device. 
     
     
         15 . The firmware providing server of  claim 12 , wherein the firmware comprises at least one subprogram, and the firmware execution code branch information is information for defining an execution sequence of the at least one subprogram. 
     
     
         16 . The firmware providing server of  claim 15 , wherein the characteristic code is linked with the at least one subprogram to be stored as the firmware. 
     
     
         17 . A system comprising:
 a data storage device; and   a firmware providing server suitable for:   performing at least one revision on firmware for the data storage device,   generating the firmware including register setting information and firmware execution code branch information, and flag information, based on the at least one revision, the flag information including attributes corresponding to versions of the firmware, and   providing the firmware and the flag information to the data storage device, and   wherein the data storage device is suitable for:   receiving the firmware and the flag information from the firmware providing server, and   executing the firmware by calling the register setting information and the firmware execution code branch information based on one attribute selected from the flag information.   
     
     
         18 . The data storage device of  claim 17 , wherein each of the attributes is generated as a program code and comprised as a part of the firmware. 
     
     
         19 . The data storage device of  claim 17 , wherein the firmware comprises at least one subprogram, and the firmware execution code branch information includes information defining an execution sequence of the at least one subprogram.
