We construct the dynamical associative memory on the switched-capacitor (SC) 400-neuron chaotic neuro-computer prototype. We observe a variety of associative dynamics from the prototype. The chaotic behavior of the dynamical association comes from complexity in real number. The analog SC chaotic neurons used in the system can handle real numbers through their continuous variables, therefore, they would faithfully reproduce the chaotic behavior. In construct, digital computers cannot handle almost all real numbers. In this respect, we analyze the measured results from the hardware system in comparison with those from computer simulations. In the computer simulation, we take into account characteristics of the analog circuit and noise.
