Two traps related leakage mechanism is proposed to explain the tail distribution of the DRAM retention characteristics. The main mode is explained by the trap assisted tunneling with one trap. We propose that the tail mode is created when the two traps are close enough to cooperate for increasing the leakage current. We calculate both the main and the tail distributions with the Monte Carlo method by using one basic equation deduced from our model for the first time.
