A method for operating a memory system includes determining whether a recovery operation is performed, when power is supplied after being interrupted, generating an internal command for checking an operation status of a memory device when a recovery operation starts, accessing at least one open memory block in the memory device in response to the internal command, checking an operation status of the at least one open memory block, programming a preset amount of dummy data on a preset number of blank pages from a boundary programmed page in the at least one open memory block, and restoring data associated with the recovery operation in the at least one open block.

Apparatus and method for reducing cell disturb in an open block of a memory system during a recovery procedure

An operating method of a memory system includes performing a boot-up operation, determining whether a sudden power-off recovery (SPOR) operation is performed successively a predetermined number of times, and performing additional SPOR operation when a predetermined waiting time elapses after performing the boot-up operation according to a result of the determining.

Memory system and operating method thereof

A method for operating a memory system includes: detecting a first erase page of a super block, which is formed of memory blocks, by scanning the super block according to a binary search scheme based on a program order in which pages in the super block are programmed; and performing a Sudden Power Off Recovery (SPOR) based on the detected first erase page.
