Abstract :
A chaotic associative memory may be constructed by coupling a network of Chua´s circuits via piecewise linear conductances. Synchronization and anti-synchronization states are used to represent binary memory patterns. The chaotic network dynamics enable the memory to wander among patterns which have non-zero correlations with the input pattern. This paper describes two discrete circuits which may be used as the basis for implementing the coupling element as proposed in Jankowski et al. (1995). Initial coupling experiments support the proposed design approaches,
