A self-organizable neural network expressing unit includes a plurality of neuron units electronically expressing nerve cell bodies, and a plurality of synapse expressing units electronically expressing synapses for coupling neuron units through programmed coupling strengths represented by synapse load values, and a control circuit for supplying a pattern of random number data as an educator data. When the pattern of random number data is generated, the neural network expressing unit carries out correction of synapse load values as in a learning mode of operation using the pattern of random number data as an educator data. The memorized internal states in the neural network expressing unit is reinforced based on a faded memory thereof, and the synapse load values are precisely maintained for a long time, resulting in a reliable neural network expressing unit.
