Crossbar resistive memory architectures enable high-capacity storage and neuromorphic computing,accurate retrieval of the stored information is a prerequisite during read operation.However,conventional electrical readout normally suffer from complicated process,inaccurate and destructive reading due to crosstalk effect from sneak path current.Here we report a memristive-photoconductive transduction(MPT)methodology for precise and nondestructive readout in a memristive crossbar array.The individual devices present dynamic filament form/fuse for resistance modulation under electric stimulation,which leads to photogenerated carrier transport for tunable photoconductive response under subsequently light pulse stimuli.This coherent signal transduction can be used to directly detect the memorized on/off states stored in each cell,and a prototype 4*4 crossbar memories has been constructed and validated for the fidelity of crosstalk-free readout in recall process.
