“…The rapid technological developments in the era of Internet of Things, sensor networks, robotics, and artificial intelligence bring new challenges to develop material systems and architectures for memory technologies with large storage capacity. − Despite intensive progress in this field, conventional voltage-driven memory lags far behind the increasing demands for high data storage density, fast transmission, and physical miniaturization designs. The state-of-the-art nonvolatile photomemory, which transduce broadband optical stimuli into electrical signals, thereby reducing the dependence on electrical programming, have emerged as a potential candidate in ultrafast, multibit data storage, and noncontact programming memory. − Material systems including inorganic materials, organic–inorganic hybrid composites, conjugated-insulated polymer blends, and block-copolymers (BCPs) have been proposed for nonvolatile photomemory in recent years. − However, the photoresponsivity and memory retention of memory comprising inorganic and composite systems strongly rely on the size control and distribution of trapping units in a nanoscale, which produce cumbersome device fabrication. − …”
