Abstract
A memory system includes a memory device and a memory controller. The memory controller includes a core processor and a built-in self-repair (BISR) logic circuit. The core processor includes a register file with a plurality of register values corresponding to a plurality of repair commands. The BISR logic circuit receives at least one of the plurality of register values from the core processor and converts the at least one of the plurality of register values into at least one of the repair commands to output the least one of the repair commands to the memory device. The core processor transmits the at least one of the plurality of register values to the BISR logic circuit in response to a firmware instruction that is output from an external firmware coupled to the memory controller.
