In order to research the total dose effects(TDEs) of very large scale integrated circuits(VLSI) storage
two kinds of SRAM and ROM storage are used as samples in radiation experiment. 60Co γ source is selected as the radiation source. According to the result of experiment
these two devices are all sensitive circuits of total dose effects. The destroy threshold is between 10k rad(si) and 15k rad(si). By cautious analysis
a credible conclusion is proved. We should not test data function only when testing the TDEs of VLSI storage
because the static consumption current and dynamic consumption current are sensitive parameter of TDEs. If we ignore these two parameter
we could not acquire credible the VLSI storage’s capability of defending irradiation. Finally
