Storage device and operating method of storage controller

A storage device comprising:

• a non-volatile memory;
• and
• a storage controller configured to control the non-volatile memory,
• wherein the storage controller comprises:
• a command and address generator configured to generate a plurality of commands and a plurality of addresses;
• a machine learning module configured to predict whether a communication error occurs in a command and an address to be provided to the non-volatile memory, based on a communication error rate of the plurality of commands and the plurality of addresses, and based on a determination error rate of the plurality of commands and the plurality of addresses;
• an error detection module configured to generate an error detection signal from the command and the address when it is predicted that the communication error has occurred;
• and
• an interface circuit configured to transmit the command, the address, and the error detection signal to the non-volatile memory when it is predicted that the communication error has occurred,
• wherein the non-volatile memory is configured to detect the communication error in the command and the address, based on the error detection signal.
