  • Patent number: 11538550
    Abstract: A memory system includes a memory medium and a memory controller. The memory medium has a second address system that is different from a first address system of a host. The memory controller performs a control operation to access the memory medium based on a command from the host. The memory controller is configured to store a second address, corresponding to an address of a read data, when an error of the read data that is outputted from the memory medium is uncorrectable and is configured to repair a region of the memory medium, designated by the second address, when the region of the memory medium that is designated by the second address is repairable.

  • Patent number: 10861577
    Abstract: A test circuit includes a built-in self-test (BIST) circuit and a built-in repair analysis (BIRA) circuit. The built-in self-test (BIST) circuit performs a test operation for a plurality of memory packages to generate fail information. The built-in repair analysis (BIRA) circuit receives the fail information from the BIST circuit to select at least one of the plurality of memory packages as a repair target memory package. The repair target memory package is selected by considering an error correction capability of an error correction code (ECC) circuit and usability of redundancy regions included in each of the plurality of memory packages.
