Storage controller executing defense code, method of operating the same, and storage device having the same

A storage controller configured to communicate with a non-volatile memory device, the storage controller comprising:

• a block manager configured to generate timestamps;
• a block status table configured to store first block status information of a first memory block of the non-volatile memory device;
• and
• a power manager configured to register a current power count value,
• wherein the block manager is configured to:
• read the first block status information;
• read the current power count value;
• generate a current timestamp based on the current power count value coinciding with a first power count value of the first block status information;
• and
• perform a read operation of the first memory block in accordance with a defense code based on an erase time period between the current timestamp and a first erase timestamp exceeding a threshold time period.

A storage device comprising:

• a non-volatile memory device comprising a first memory block;
• and
• a storage controller configured to communicate with the non-volatile memory device,
• wherein the storage controller comprises:
• a block manager configured to generate timestamps;
• a block status table configured to store first block status information of the first memory block;
• and
• a power manager configured to register a current power count value,
• wherein the block manager is further configured to:
• read the first block status information;
• read the current power count value;
• generate a current timestamp based on the current power count value coinciding with a first power count value of the first block status information;
• and
• perform a read operation of the first memory block in accordance with a defense code based on an erase time period between the current timestamp and a first erase timestamp exceeding a threshold time period.
