Abstract
An apparatus, system, and method are disclosed for accessing redundant data. A verification value module calculates a first verification value for a first redundant memory. In addition, the verification value module calculates a second verification value for a second redundant memory. In one embodiment, a validation module validates the first and second verification values. A selection module accesses the first redundant memory if the first verification value is equivalent to the second verification value. In a certain embodiment, the selection module identifies and accesses the redundant memory with a most advanced generation count if the first and second verification values are valid and are not equivalent.
