Abstract
A method comprising of allocating a main memory partition and a mirrored memory partition, a mirrored copy of the main memory partition, of a mirrored memory system for scrubbing. The method also comprises of dividing the main memory partition into a first main portion and a second main portion and dividing the mirrored memory partition into a first mirrored portion and a second mirrored portion. The method determines a full scrub cycle that only scrubs a portion of the main memory channel and a portion of the mirrored memory partition, the full scrub cycle including scrubbing a main scrub portion, one of the first and the second main portions, and a mirrored scrub portion, one of the first and the second mirrored portions. The method initiates the full scrub cycle which includes a combination of memory portions, equivalent to a memory address range of the main memory partition.
