Apparatus, system, and method for operating memory system

A memory system, comprising:

• a memory device;
• and
• a memory controller configured to:
• in response to determining a power-off occurrence of the memory system, initiate a power-off recovery (POR) procedure;
• and
• in response to determining that a read error occurs during the POR procedure:
• acquire a plurality of first read-retry levels, the plurality of first read-retry levels being a portion of a plurality of second read-retry levels that are applied, during a standard read error handling procedure, in one or more second read-retry operations on the memory device;
• and
• send a first address signal and a first instruction signal to the memory device to perform one or more first read-retry operations on the memory device, the first instruction signal being generated based on the plurality of first read-retry levels.
