Some sufficient conditions for the existence and globally exponential stability of unique equilibrium point are established using fixed point theorem and differential inequality techniques. The results obtained are easily checked to guarantee the existence uniqueness and globally exponential stability of equilibrium point.

It is a special class of recurrent neural networks that can store bipolar vector pairs. The BAM neural network is composed of neurons arranged in two layers the X-layer and Y-layer. The neurons in one layer are fully interconnected to the neurons in the other layer while there are no interconnections among neurons in the same layer. Through iterations of forward and backward information flows between the two layers it performs two-way associative search for stored bipolar vector pairs and generalize the single-layer autoassociative Hebbian correlation to two-layer pattern-matched heteroassociative circuits. Therefore this class of networks possesses a good .
