An Analog Floating-Gate Node for Supervised Learning.

We present an improved analog floating-gate pFET synapse that implements a supervised leaning algorithm similar to the least mean square (LMS) Learning rule. Weight decay plays a key role in several learning rules; this floating-gate synapse exhibits this behavior. We examine implications of the weight decay appearing in the correlation learning rule realized in the floating-gate synapse and provide experimental data characterizing the synapse and its performance in one-input and two-input LMS networks. Analog floating-gate synapses will enable larger-scale, on-chip learning networks than previously possible. [ABSTRACT FROM AUTHOR]
