Abstract: A method for adaptively setting analog weights in analog cells of a neural network and the like. The process starts by addressing a synapse cell in the network. A target weight for said addressed synapse cell is selected, and the current weight present on the synapse cell is measured. The amplitude and duration of a voltage pulse to be applied to said synapse cell to adjust said synapse cell in the direction of said target weight is calculated using a set of coefficients representing the the physical characteristics of the synapse cell. The voltage pulse is applied to the addressed synapse cell and the new weight of the synapse cell is re-measured. If the synapse cell weight is within acceptable limits of the target weight, the values of the coefficients are saved and the next adjacent synapse cell is addressed until all synapse cells are set. If the synapse cell is not within acceptable limits, new values for the coefficients are calculated in relation to the re-measured weight.
