Abstract
Abstract Phase change memory emerges as one of the most promising alternatives to traditional DRAM in terabyte main memory constructions. 3D stacking technology further enhances the scalability and capacity of PCM. However, write bandwidth of emerging 3D stacked PCMs is seriously limited by capacitive change pump widely adopted in 2D PCM chips. In this paper, we propose an inductive charge pump system design for 3D stacked PCMs. We further present a novel ICP aware page management technique to reduce ...
