N2 - The retrieval process of an associative memory with a general input-output function is studied by means of a signal-to-noise ratio analysis. We derive a set of recursion relations for macroscopic variables to describe the time development of the network. By taking equilibrium limit of the recursion relations, we find that a certain type of non-monotonic input-output relation of a single neuron yields an enhanced memory capacity than the conventional monotonic relation. This result combined with Monte Carlo simulations confirms the prediction of Morita et al and reveals new aspects in the retrieval process.
