Zusammenfassung: | A test operation condition of a volatile memory device is set such that an error probability is increased based on the test operation condition, compared to a normal operation condition for a normal operation of the volatile memory device. A test mode is set with respect to a test object region corresponding to at least a portion of a memory cell array included in the volatile memory device. A test operation of the volatile memory device is performed based on the test operation condition during the test mode to detect error position information of errors in data stored in the test object region. A runtime repair operation is performed with respect to the volatile memory device based on the error position information. |
