Abstract
A method for updating a weight of a synapse of a neuromorphic device is provided. The synapse may include a transistor and a memristor. The memristor may have a first electrode coupled to a source electrode of the transistor. The method may include inputting a row spike to a drain electrode of the transistor at a first time; inputting a column spike to a second electrode of the memristor at a second time; inputting a row pulse to the drain electrode of the transistor at a third time that is delayed by a first delay time from the second time; inputting a column pulse to the second electrode of the memristor at a fourth time that is delayed by a second delay time from the second time; and inputting a gating pulse to a gate electrode of the transistor at a fifth time that is delayed by a third delay time from the fourth time.
