Abstract
A memory system and an operating method thereof are disclosed. An operating method of a memory system including a nonvolatile memory device and a controller configured to control the nonvolatile memory device includes the controller updating original data of firmware stored in the nonvolatile memory device, the controller transmitting a notification signal, which notifies a host device of completion of the updating of the original data, to the host device when the updating of the original data is completed, and the controller updating backup data of the firmware stored in the nonvolatile memory device after the notification signal is transmitted.
Claims14
An operating method of a memory system including a memory device and a controller, the method comprising:
- updating, by the controller, original data of firmware stored in the memory device;
- transmitting, by the controller, a notification signal, which notifies a host device of completion of the updating of the original data, to the host device when the updating of the original data is completed;
- updating, by the controller, backup data of the firmware stored in the memory device after the notification signal is transmitted, and
- rebooting the memory system based on updated original data when sudden power off (SPO) occurs after the notification signal is transmitted to the host device and before the updating of the backup data is completed,
- wherein the updating of the backup data is performed after the memory system is rebooted based on the updated original data.
A memory system comprising:
- a memory device configured to store original data and backup data of firmware;
- and
- a controller configured to control the memory device,
- wherein the controller controls the memory device to update the original data of the firmware, transmit a notification signal, which notifies a host device of completion of the updating of the original data, to the host device when the updating of the original data is completed, and update the backup data of the firmware after the notification signal is transmitted, and
- wherein when sudden power off (SPO) occurs after the notification signal is transmitted to the host device and before the updating of the backup data is completed, the controller reboots the memory system based on updated original data and controls the memory device to update the backup data after the rebooting is completed.
