Abstract
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.
