A chaotic neural network consisting of chaotic neurons exhibits such rich dynamical behaviors
as nonperiodic associative memory. But it is difficult to distinguish the stored
patterns from others, since the chaotic neural network shows chaotic wandering around the stored
patterns. In order to apply the nonperiodic associative memory to information search or pattern
identification, it is necessary to control chaotic dynamics. In this paper, we propose a delay
feedback control method for the chaotic neural network. Computer simulation shows that, by means
of the control method, the chaotic dynamics in the chaotic neural network are changed. The
output sequence of the controlled network wanders around one stored pattern and its reverse pattern
