In order to correct the shortcomings of the former brain storage model, an improved brain storage model was proposed, it consisted of a memory bank and a series of sub-storages. These sub-storages were concluding sub-storage, effective search sub-storage, storing sub-storage, recalls sub-storage and forgetting sub-storage. The input formation of the improved brain storage model was single fuzzy cognitive unit event. Experimental results demonstrated that the model was able to simulate storage functions of the brain, such as concluding, storing, recalling and forgetting. So the improved brain storage model is optimal.
