Abstract
Mirrored memory scrubbing is optimized to reduce system power consumption and increase system performance. A memory scrub operation scrubs a first portion of the mirrored memory to detect and correct soft errors. The scrub rate of a second portion of the mirrored memory is eliminated, minimized, or reduced, relative to the scrub rate of the first portion. The reduced scrub operation preserves power consumed in association with scrubbing the second portion.
