In this paper we describe an analog VLSI circuit, fabricated using a standard 2 µm, n-well, BiCMOS process,which utilizes floating-gate structures for non-volatile, on-chip,analog parameter storage. This circuit is designed to operate in the context of a hardware model of the primate oculomotor system and performs visually-guided, saccadic adaptation. The chip contains a one-dimensional array of photoreceptors and floating-gate circuits which are used to map retinal positions to motor output commands. The system's functionality is demonstrated by training the chip with several different mapping functions using a supervised-learning technique.
