1. A method for training a memristive neuromorphic circuit, the method comprising: providing a conductance balanced voltage pair that includes a set voltage and a reset voltage, wherein either one of the set voltage and the reset voltage, when applied to a memristive device that is connected to a neuron circuit, effects a substantially same magnitude conductance change in the memristive device over a predetermined range of conductance of the memristive device; storing the provided voltage pair as a conductance balanced map; and applying, based on the conductance balanced map, a training voltage to the memristive device.
