Multi-sensory　neuromorphic　devices　(MND)　have　broad　potential　in　overcoming　the　structural　bottleneck　of　von　Neumann　in　the　era　of　big　data.　However,　the　current　multisensory　artificial　neuromorphic　system　is　mainly　based　on　unitary　nonvolatile　memory　or　volatile　synaptic　devices　without　intrinsic　thermal　sensitivity,　which　limits　the　range　of　biological　multisensory　perception　and　the　flexibility　and　computational　efficiency　of　the　neural　morphological　computing　system.　Here,　a　temperature-dependent　memory/synaptic　hybrid　artificial　neuromorphic　device　based　on　floating　gate　phototransistors　(FGT)　is　fabricated.　The　CsPbBr3/TiO2　core—shell　nanocrystals　(NCs)　prepared　by　in-situ　pre-protection　low-temperature　solvothermal　method　were　used　as　the　photosensitive　layer.　The　device　exhibits　remarkable　multi-level　visual　memory　with　a　large　memory　window　of　59.6　V　at　room　temperature.　Surprisingly,　when　the　temperature　varies　from　20　to　120　°C　back　and　forth,　the　device　can　switch　between　nonvolatile　memory　and　volatile　synaptic　device　with　reconfigurable　and　reversible　behaviors,　which　contributes　to　the　efficient　visual/thermal　fusion　perception.　This　work　expands　the　sensory　range　of　multisensory　devices　and　promotes　the　development　of　memory　and　neuromorphic　devices　based　on　organic　field-effect　transistors　(OFET).　[Figure　not　available:　see　fulltext.]　©　2023,　Tsinghua　University　Press.
