Design of Coupled Nonlinear Systems for Storage of Prescribed Binary Patterns

In this paper, we investigate synchronization and cluster formation phenomena in two-dimensional arrays of locally interconnected chaotic circuits. We report the existence of an abundance of attractors, for which each cell stores a binary information. We describe a simple method for storing binary patterns in the network. We also address the question which patterns can be successfully stored in the network and discuss problems of pattern stability and influence of parameters mismatch.
