Memory controller performing recovery operation using recovery code and operating method thereof

A method for operating a memory controller for controlling a data storage device, the method comprising:

• generating power sensing information by sensing a power consumption of the data storage device;
• determining an operation mode of the data storage device as a normal mode or a sleep mode according to the power sensing information;
• and
• storing a recovery code address indicating a position at which a recovery code is stored and a normal code address indicating a position at which a normal code is stored, based on the operation mode of the data storage device.

An operating method of a controller for controlling a memory device, the operating method comprising:

• copying a code address from a first memory to a second memory when the memory device enters a first mode;
• performing a recovery operation on the memory device by executing a recovery code when the memory device exits the first mode and enters a second mode;
• and
• performing a normal operation on the memory device by executing a normal code when the recovery operation is succeeded,
• wherein the recovery code is stored in a nonvolatile memory region indicated by the code address and the normal code is stored in a volatile memory region indicated by the code address, and
• wherein the first and second memories are included in the controller.
