Memory effects are a classic feature of disordered materials. With Raman-microspectroscopy we evidence a memory effect in the deformation of densified soda-lime silicate glasses, and with molecular dynamics simulations we identify the network reconfigurations it originates from. These results pave the way toward a better understanding of plastic instability, damage, and rupture properties in iono-covalent glassy materials.
