Embodiments of the present disclosure provide a neuromorphic circuit structure including: a first vertically-extending neural node configured to generate an output signal based on at least one input to the first vertically-extending neural node; an interconnect stack adjacent the vertically-extending neural node, the interconnect stack including a first conducting line coupled to the first vertically-extending neural node and configured to receive the output signal, a second conducting line vertically separated from the first conducting line, and a memory via vertically coupling the first conducting line to the second conducting line; and a second vertically-extending neural node adjacent the interconnect stack, and coupled to the second conducting line for receiving the output signal from the first vertically-extending neural node.
