A memory system includes: a storage device for storing data; a system memory in which normal firmware and debugging firmware are stored; a firmware implementer for implementing the normal firmware or the debugging firmware; and a controller for controlling the storage device in a normal mode in which the memory system is driven by the normal firmware. When an error detected in the normal mode is uncorrectable, the controller uploads the debugging firmware stored in the system memory to the firmware implementer to change the normal mode to a debugging mode. The firmware implementer performs a debugging operation on the storage device by implementing the uploaded debugging firmware.

Memory system and operation method of the memory system

Embodiments of the present disclosure relate to a memory system and an operating method of the memory system. According to embodiments of the present disclosure, when updating a target firmware, a memory system may receive, from a host, a temporary firmware for increasing the size of a buffer from a preset first size to a second size equal to or greater than the size of the target firmware, may load and execute the temporary firmware into a processor, may receive the target firmware from the host and write the target firmware to the buffer, and may write the target firmware to the memory device.
