Many memory cell technologies are being considered as possible replacements for DRAM and Flash technologies, both of which are nearing their scaling limits. While these new cells promise high density, better scaling, and non-volatility, they introduce new challenges. Solutions at the architecture level can help address some of these problems; e.g., prior research has proposed wear-leveling and hard error tolerance mechanisms to overcome the limited write endurance of PCM cells. In this paper, the authors focus on the soft error problem in PCM, a topic that has received little attention in the architecture community.
