PURPOSE:To prevent the production of soft errors through an alpha-ray by using a signal obtained via a set/reset latch from an affirmative and negative output as a feedback signal. CONSTITUTION:A signal being the result or ORing an output of a set/reset latch (RS latch) 11 using the affirmative output signal Q and the negative output signal, the inverse of Q as the set and reset inputs respectively and the affirmative output signal Q or the negative output signal, the inverse of Q, is used as a feedback signal. That is, in using the RS latch 11 comprising the NOR gate in place of a conventional NOR gate, the latch 11 is set or reset by the H level input and the signal is transmitted and not inverted by the L level input (in holding state). Thus, an error signal where the output goes from L to H level is not caused. Thus, the flip-flop circuit not causing any soft error due to the incident of an alpha ray is realized. |
