Memory system for optimizing parameter values according to workload class and data processing system including the same

An operation method of a data processing system including a memory system and an external device, the memory system including a specific storage space having nonvolatile characteristics and the external device for controlling an operation of the memory system, the operation method comprising:

• generating, by a test on the memory system performed in an external test device, workload information including groups of parameter values in a table form, the groups corresponding to respective workload classes;
• storing, by the memory system, the workload information in the specific storage space;
• determining, by the external device, one of the plurality of workload classes as a determined class;
• generating, by the external device, a set command at a ratio corresponding to the determined class;
• outputting, by the external device, the set command to the memory system;
• detecting, by the memory system, the ratio of the set command inputted from the external device;
• selecting, by the memory system, one of the plurality of workload classes as a detected class according to a result of the detecting the ratio;
• processing, by the memory system, the set command under an execution condition determined by applying the group corresponding to the detected class from the workload information;
• detecting, by the external device, a performance result of the memory system through a result of the processing;
• generating, by the external device, parameter values corresponding to the performance result;
• outputting, by the external device, the parameter values corresponding to the performance result to the memory system;
• and
• updating, by the memory system, the parameter values corresponding to the detected class with the parameter values inputted from the external device.

A data processing system comprising:

• a memory system configured to
• store, in an internal specific storage space having nonvolatile characteristics, workload information including groups of parameter values in a table form, the groups corresponding to respective workload classes,
• detect a ratio of a set command inputted from an external device in a set operation mode,
• select one of the plurality of workload classes as a detected class according to a result of the detecting the ratio,
• process the set command under an execution condition determined by applying the group corresponding to the detected class from the workload information, and
• update the group corresponding to the detected class with parameter values inputted from the external device;
• and
• the external device configured to
• generate the set command at the ratio corresponding to one determined class of the plurality of workload classes,
• output the set command to the memory system, detect a performance result of the memory system through a result of the processing,
• generate the parameter values corresponding to the performance result, and
• output the parameter values to the memory system.
