Abstract
Abstract: Driven by the trends of increasing core-count and bandwidth-wall problem, the size of last level caches has greatly increased, and hence the researchers have explored non- volatile memories (NVMs) that provide high density and consume low-leakage power. Since NVMs have low write endurance and the existing cache management policies are write variation (WV) unaware, effective wear-leveling techniques (WLTs) are required for achieving reasonable cache lifetimes using NVMs. We present EqualWrites, a technique ...
