Compact EEPROM-based Weight Functions

The recent surge of interest in neural networks and parallel analog computation has motivated the need for compact analog computing blocks. Analog weighting is an important computational function of this class. Analog weighting is the combining of two analog values, one of which is typically varying (the input) and one of which is typically fixed (the weight) or at least varying more slowly. The varying value is "weighted" by the fixed value through the "weighting function", typically multiplication. Analog weighting is most interesting when the overall computational task involves computing the "weighted sum of the inputs."
