An apparatus for simulating the behavior of a biological neuron. A chargecarrying component is fabricated from semiconductor material and is disposed above a semiconductor substrate. The charge-carrying component is separated from the substrate, and substantially surrounded, by an isolating material, such as an oxide (e.g., silicon dioxide). In order to control the quantity of charge carried on the charge-carrying component, a charge injector (104) is disposed adjacent to the charge-carrying component and is configured to controllably transfer charge to the charge-carrying component. Similarly, a drain (106) is disposed adjacent to the charge-carrying component and configured to controllably transfer charge away from the charge-carrying component. The charge injector (104) and drain (106) of the preferred embodiment are structurally similar to charge injectors and drains conventionally used in EEPROM technology. To generate an output, a charge sensor (116) disposed in proximity with a charge sensing location on the charge-carrying component, and an output (130) is provided and disposed in communication with the charge sensor (116). As a result, the output delivers an electric signal that is indicative of the charge sensed by the charge sensor.
