  • Patent number: 11907064
    Abstract: A memory controller includes a fault predictor which predicts a fault which causes an error occurring in a memory device, an error correction code (ECC) manager which classifies a type of the fault based on the predicted fault, and a plurality of ECC engines which perform ECC in parallel depending on the classified type of the faults. The fault predictor includes a memory error profiler which receives raw data related to the error and processes the raw data into an error profile that is data available for machine learning, and a memory fault prediction network which receives the error profile as an input, performs the machine learning using the error profile, and predicts the fault which causes the error.
