Abstract
A neural network providing correlation learning in a synapse cell coupled to a circuit for parallel implementation of weight adjustment provides the learning portion of the synaptic operation and includes a floating gate device having a corresponding floating gate member that stores the connection weight of the cell. Parallel weight adjustments are performed in a single operational cycle utilizing floating gate technology and control signals that facilitate programming/erasing operations.
