Power management of caches based on turning idle cache lines into a low-energy state is also beneficial for the aging effects caused by Negative Bias Temperature Instability (NBTI), provided that idleness is correctly exploited; unlike energy, aging, being a measure of delay, is in fact a worst-case metric. In this paper the authors propose an application-specific partitioned cache architecture in which a cache is organized as a set of independently addressable sub-blocks; by properly using the idleness of the various banks to drive how the partition is determined, it is possible to extend the effective lifetime of the cache while saving extra energy.
