A memory controller controls a data storage device including a nonvolatile memory in which a recovery code is stored. The memory controller includes: a mode converter for determining an operation mode of the data storage device as a normal mode or a sleep mode, according to power sensing information representing a power consumption of the data storage device, a recovery code storage including a nonvolatile memory, in which a recovery code for a recovery operation is stored, and a code executer for performing the recovery operation by executing the recovery code. The mode converter stores a recovery code address indicating a position of the nonvolatile memory at which the recovery code is stored.

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

A memory system includes a memory device and a controller. The controller includes: a first internal storage, a second internal storage configured to store a recovery code, a level detector configured to detect whether a change in levels of power supply voltages exceeds respectively reference level ranges, a protection operation component configured to determine entry into and exit from a protection mode in response to a result of the level detector, to perform a first protection operation of generating event information and a snapshot information and storing the event and snapshot information in the first internal storage, and a recovery operation component configured to receive the recovery code from the second internal storage in response to exiting from the protection mode, to enter the recovery mode, to receive the event information and the snapshot information from the first internal storage, and to perform a recovery operation on the memory device.
