While conductive domain walls have been discovered in many materials, progress in the field is hindered by high-voltage operations, stability of the resistive states and limited control over the domain wall dynamics. Here, we show nonvolatile memristive functionalities based on precisely controllable conductive domain walls in tetragonal Pb(Zr,Ti)O3 thin films within a two-terminal parallel-plate capacitor geometry. Individual submicron domains can be manipulated selectively by position-sensitive low-voltage operations to address distinct resistive states with nanoampere-range conduction readout. Quantitative phase-field simulations reveal a complex pattern of interpenetrating a- and c-domain associated with the formation of 2D conducting layers at the intertwined regions and the emergence of 3D percolation channels of extraordinary high conductivity. Subnanometer resolution polarization mapping experimentally proves the existence of such extensive segments of charged tail-to-tail domain walls with unconventional structure at the ferroelastic-ferroelectric domain boundaries.2025http://zaguan.unizar.es/record/15120310.1021/acsnano.4c14727http://zaguan.unizar.es/record/151203oai:zaguan.unizar.es:151203info:eu-repo/grantAgreement/ES/AEI/CEX2023-001286-Sinfo:eu-repo/grantAgreement/ES/DGA/E13-23Rinfo:eu-repo/grantAgreement/ES/DGA-FEDER E28-23Rinfo:eu-repo/grantAgreement/EC/H2020/ 861153/EU/Materials for Neuromorphic Circuits/MANICThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 861153-MANICinfo:eu-repo/grantAgreement/EC/H2020/872631 /EU/Memristive and multiferroic materials for emergent logic units in nanoelectronics/MELONThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 872631 -MELONinfo:eu-repo/grantAgreement/ES/MICINN-AEI/PID2020-112914RB-I00info:eu-repo/grantAgreement/ES/MICINN/PID2023-147211OB-C22ACS NANO 19, 7 (2025), 6993-7004byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
