Abstract: A family of chaotic bidirectional associative memory models (C-BAM
family) is introduced through the inclusion of the chaotic neuron in the
original BAM family. Each parameter in the chaotic neuron has its influence
upon the distinct dynamics estimated throughout experimental design. Based on
this analysis, values of parameters are set to illustrate the existence of
behaviors such as bifurcation, deterministic chaos and crisis. The existence of
the chaotic dynamics is confirmed by calculation of Lyapunov exponents. C-BAM
family also presented diversity of patterns recalled, including the occurrence
of excursions over all stored memories for some sets of parameters. Hence,
C-BAM family can access patterns that original BAM family cannot.
