1. A semiconductor neuron, comprising: at least one input electrode, consisting of a plurality of partial electrodes, coupled capacitively for signal transmission to a floating gate whose potential controls a current of a MOS field effect transistor; a respective neuron input being connectable to partial electrodes of the plurality of partial electrodes such that a total surface area of the partial eltrodes connected to the respective neuron input corresponds to a respective weight of the respective neuron input, and whereby sub-electrodes of the input electrodes are connected to neuron inputs via multiplexers.
