SIM-PCM: A PCM Simulator Based on Simics

Phase change memory (PCM) is an emerging memory technology which fast, byte-addressable and non-volatile. Because of these attractive features, PCM is the most promising technology to replace DRAM as main memory. Also, PCM provides new challenges for researchers to integrate it in the system memory hierarchy. Currently, there are several approaches provided to leverage the features of PCM to improve the performance of system. However, as PCM is not available in the market, current researches could only use DRAM to simulate PCM. What is more, there are no researches to simulate the full features of PCM. In this paper, we design and implement SIMPCM, a device-level PCM simulator. SIM-PCM is the first PCM Simulator that supports PCM features including latency and non-volatility. Also, SIM-PCM is very easy to use.
