  • Patent number: 11650752
    Abstract: A computing system includes: a memory device including a memory cells; a memory controller configured to control the memory device; and a host configured to detect an occurrence of an error in a first memory cell of the memory device while performing an operation corresponding to a workload and transmit, to the memory controller, a target address corresponding to the first memory cell and a request for a test operation on adjacent memory cells that are adjacent to the first memory cell. The memory controller controls the memory device to perform the test operation on the adjacent memory cells by using at least one of a Built-In Self-Test (BIST) engine or a scrub engine based on the target address and generate memory error information including information associated with a second memory cell in which the error occurs, the second memory cell being one of the adjacent memory cells. The host controls an access to the second memory cell based on the memory error information.
