Controller to detect malfunctioning address of memory device

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 a 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.

A memory controller comprising:

• a non-volatile memory component;
• and
• a memory control unit coupled to the non-volatile memory component, the memory control unit to perform operations 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 a 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.
