As wide application of EEPROM devices in space and military field, more and more researches focus on its radiation hardened characteristics in international. To improve the single-event effect (SEE) tolerant ability of read-out circuits in the memory, a radiation hardened circuit is designed. The design kernels of radiation hardened latch-flip are given and designed to resist the single-event upset (SEU) effect. A correction circuit is proposed to resist the single-event transient (SET) effect. The performances of this design are: SEU (LET)th ≥ 27 MeV•cm2/mg, SEL(LET)th ≥ 75 MeV•cm2/mg , read out time ≤200 ns. The new design not only satisfied the needs of present work, but supplies a worthful reference for radiation hardened circuit design in future.
