Lees multivalued bidirectional associative memory operating on a complex domain (CDBAM) extends Koskos BAM (bidirectional associative memory) not only to complex domain but also to multivalued situation in favor of associating on multivalued model. Based on the CDBAM, a new extended model, ICDBAM (intraconnected multivalued bidirectional associative memory operating on a complex domain), is presented in this paper. The stability of the new model in synchronous and asynchronous updating modes, is proven by defining an cenergy function such that it can ensure all the training pattern pairs to become its asymptotically stable points.Inaddition,it eliminates CDBAM's complementing encoding problem.The computer simulations show that the proposed model has higher storage capacity and better error-correcting calability than CDBAM.
