Here we present an experimentally feasible quantum memory for individual polarization photon with long-lived atomic ensembles excitations. Based a process similar to teleportation, the memory is reversible. And the storage information can be effortlessly read out and transferred back to photon. Although it successes with only a probability of 1/4, it is expected valuable in various quantum information processing, especially those cases where polarized photons are employed. The physical requirements are moderate and fit the presest technique.
