Abstract
A memory system includes: a memory device suitable for storing system operating information; and a controller suitable for performing a check-pointing operation whenever a background operation is to be performed, performing the background operation based on the system operating information, and performing a roll-back operation based on the system operating information stored by the check-pointing operation at a time right before the background operation is performed when an error occurs during the background operation, wherein the controller performs the roll-back operation by reflecting error information on the error into the system operating information, and performing the background operation based on the system operating information with the error information reflected therein.
Claims20
A memory system, comprising:
- a memory device suitable for storing system operating information;
- and
- a controller suitable for performing a check-pointing operation whenever a background operation is to be performed, performing the background operation based on the system operating information, and performing a roll-back operation based on the system operating information stored by the check-pointing operation at a time right before the background operation is performed when an error occurs during the background operation,
- wherein the controller performs the roll-back operation by reflecting error information on the error into the system operating information, and performing the background operation based on the system operating information with the error information reflected therein.
A method for operating a memory system, comprising:
- performing a check-pointing operation whenever a background operation is to be performed;
- performing the background operation based on system operating information;
- and
- performing a roll-back operation based on the system operating information stored by the check-pointing operation at a time right before the background operation is performed when an error occurs during the background operation,
- wherein the performing of the roll-back operation includes
- reflecting error information on the error into the system operating information obtained by the check-pointing operation, and performing the background operation based on the system operating information with the error information reflected therein.
