Utilizing a honeycomb lattice photonic crystal, the memory leverages topologically protected edge states that remain robust against fabrication imperfections and environmental perturbations. By applying a synthetic time-dependent magnetic field, we achieve real-time tunability of the Chern number, enabling rapid and efficient memory switching without the need for light-trapping mechanisms.
