Electronic device managing computing powers of peripheral electronic devices and operating method of electronic device

An electronic device comprising:

• a nonvolatile memory device;
• and
• a controller configured to communicate with an external interface bus and to control the nonvolatile memory device,
• wherein the controller is configured to receive a combined program code from the external interface bus, the combined program code including a plurality of program codes and including a plurality of micro codes corresponding to the plurality of program codes, each micro code of the plurality of micro codes corresponding to a type of the electronic device,
• wherein the controller is configured to store a corresponding program code of the plurality of program codes of the combined program code, in order to change an operation of the controller according to the corresponding stored program code of the plurality of program codes, and
• wherein the controller is configured to sequentially execute the plurality of micro codes to identify the corresponding program code.

An operating method of an electronic device which includes a nonvolatile memory device and a controller, the operating method comprising:

• receiving, at the controller, a combined program code from an external interface bus, the combined program code including a plurality of micro codes and a plurality of program codes corresponding to the plurality of micro codes, each micro code of the plurality of micro codes corresponding to a type of the electronic device;
• storing, at the controller, a corresponding program code of the plurality of program codes, in order to change an operation of the controller according to the corresponding stored program code of the plurality of program codes;
• and
• identifying, at the controller, one of the plurality of program codes corresponding to the type of the electronic device by sequentially executing the plurality of micro codes.
