A neuromorphic device with a three-dimensional stacked synaptic structure comprises: a plurality of unit synaptic modules; a decoder providing a level selection signal to a unit synaptic module to be accessed among the unit synaptic modules; and a decoder generating a memristor address to be accessed in the memristor array of a synaptic layer included in the unit synaptic module to be accessed.
