A light-programmed rewritable lattice-mediated multistate memory for high-density data storage

DOI:10.1002/adma.202302318

A multi-time programmable non-volatile memory is realized by utilizing light programming on a ReS₂ device. The device exhibits more than 128 extremely stable states with linearly increasing conductance and shows superior wavelength discrimination capability. This device represents a significant contribution to memory technology by offering the ability to store information in multistate memory and enabling filter-free color image recorder applications.
