Register having irradiation-resistant function

The present invention discloses a register having a function of anti-irradiation, the present invention is directed to a conventional radiation resistance can not register unit function proposed suppressing effect and problems SET SEU effects simultaneously. Register of the present invention comprises: a delay unit, an inverter, a gate protection circuit, a first latch and a second latch unit cell. Register with anti-radiation function of the present invention through the latch acting to inhibit cell structure SEU effects, there is a self-protection loop inside of the latch unit when a node under attack, does not result in inversion logic state; SET suppression effect achieved by the delay unit, and a gate circuit protection filtering effect can be suppressed while the SET and SEU effects, may be applied to a very harsh environment of space.
