Phase-change RAM (PCM) has the advantages of better scaling and non-volatility compared with the DRAM which is expected to face its scaling limit in the near future. There have been many studies on applying the PCM to main memory in order to complement or replace the DRAM. One common limitation of these studies is that they are based on synthetic PCM models. In this paper, the authors investigate the feasibility and issues of applying a real PCM to main memory. In this paper, they report their case study of characterizing the PCM and evaluating its usefulness in the main memory.
