Systems and methods for decoding error correcting codes with historical decoding information

A storage system controller, comprising:

• a decoder configured to receive a first chunk of data read from a physical location of a non-volatile storage device and decode the first chunk of data;
• a soft information fetcher configured to:
• search a memory for soft information associated with the physical location using a unique identifier associated with the physical location;
• and
• retrieve the soft information identified by the unique identifier associated with the physical location from the memory, wherein the decoder is further configured to decode the first chunk of data with the soft information indicating reliability of bits in the first chunk of data;
• and
• a soft information generator configured to generate updated soft information associated with the physical location using the soft information and decoding information generated by the decoder during decoding the first chunk of data and configured to store the updated soft information in the memory.

A non-transitory machine-readable medium having executable instructions, wherein the executable instructions, when executed by a storage controller, causes the storage controller to:

• receive a first chunk of data read from a physical location of a non-volatile storage device;
• search a memory for soft information associated with the physical location using a unique identifier associated with the physical location;
• retrieve the soft information identified by the unique identifier associated with the physical location from the memory;
• decode the first chunk of data with the soft information indicating reliability of bits in the first chunk of data;
• generate updated soft information associated with the physical location using the soft information and decoding information generated during the decoding of the first chunk of data and store the updated soft information in the memory.
