Abstract
Embodiments relate to performing a memory scrubbing operation that includes injecting an error on a write operation associated with a memory address. One or more errors are detected during a two-pass scrub operation on the memory address. Based on a result of the two-pass scrub operation, one or more of a hard error counter associated with the memory address and a soft error counter associated with the memory address is selected. The one or more selected counters are updated based on the result of the two-pass scrub operation.
