The two networks are connected irreversibly, the 4\u2032\u2010acetamidoflavylium being transformable into the 4\u2032\u2010aminoflavylium by means of a heat input in extremely acidic solutions. The possibility of performing several different <jats:italic>write\u2010read\u2010erase<\/jats:italic> cycles, as models for optical memories operating by different algorithms, is discussed. An upper level of operation of these photochromic devices in which the algorithms are used as inputs to switch between the several memory cycles is proposed.
