    We investigate the modulation of the localized surface plasmon resonance (LSPR) of a gold nanorod (AuNR) using a GeSbTe film\nas an active medium. We demonstrate high-contrast switching of LSPR in an AuNR/GST/Au thin film sandwich structure upon\nphase change. To go beyond this single-particle switching functionality, we consider a plasmon particle system interacting with\na phase-change material (PCM) to discuss the possibility of parallel processing devices with memory functionality, exploiting the\nplasticity and threshold behavior that are inherent characteristics of PCMs.We demonstrate that the temporal and spatial evolution\nof a plasmon-PCM array system can be equivalent to a cellular automata algorithm.
