Abstract
In some embodiments, a computer-implemented method includes maintaining two or more error indicators for correctable errors occurring at two or more memory components. Each of the error indicators may be associated with a corresponding memory component. A correctable error may be detected as occurring during a first memory fetch operation at a first memory component. A first error indicator corresponding to the first memory component may be set, responsive to the correctable error at the first memory component. An uncorrectable error may be detected during a second memory fetch operation. It may be detected that the first error indicator is set. The first memory component may be marked, responsive to the uncorrectable error and to detecting that the first error indicator is set. The two or more error indicators for correctable errors may thus determine which memory component to mark due to the uncorrectable error.
