1. A method of operating a memory controller comprising a non-volatile memory component, the method comprising:
determining whether the non-volatile memory component stores a malfunctioning memory address to be repaired in a volatile memory device coupled to the memory controller;
in response to determining that the non-volatile memory component stores the malfunctioning memory address to be repaired, sending an indication of the malfunctioning memory address to a repair circuit of the volatile memory device coupled to the memory controller; and
activating an address matching register of the repair circuit in the volatile memory device, wherein the address matching register corresponds to the malfunctioning memory address.
