We first study the dark-state polaritons of the three- Λ EIT atom system with three quantized fields and three classical control fields. Then we focus on the storage mechanism and the quantum effect of this system. With this scheme, not only the three-mode quantum information but also some tripartite entangled states can be generated, stored, retrieved and transformed, thus the ability of the manipulation of entangled states is improved.
