Abstract :
Presents the building blocks for an analog continuous-time micropower CMOS Hopfield associative memory with local adaptation and storage of weights, a synaptic connection circuit, an analog memory, a memory programming circuit and an artificial neuron. The building blocks are modular, allowing a net of any size to be built. The weight adaption is by the outer product rule. The analog memory works by exposure to UV-light. A six neuron net, intended for storage and retrieval of two patterns, was implemented in a standard 2μm CMOS process
