Reliable Latency Extraction with NVSim Revision in Emerging NVM (ITC-CSCC 2019)

In this paper, the reliability and practicality of NVSim, which provides the performances of non-volatile memory to the system level, are improved. Since the conventional NVSim does not reflect the actually used technology or sense amplifier information, the latency among the extracted parameters from NVsim shows the biggest difference from that available in the industry. In order to solve this problem, NVsim is revised such that more reliable and practical data is reflected to NVSim according to the memory configuration. Thus, performances extracted from the proposed NVsim can be applied accurately according to the memory configuration. The simulation results using the proposed NVSim is compared with the actual results of the currently published NVM and it is confirmed that the proposed NVSim improves the accuracy by ~ 57% compared with the conventional NVM.
