The operation principle of the present invention:The latch structure that a kind of anti-SEU of the present invention is reinforced includes data write operation and guarantor
Hold operation.Data write operation is:(1) as clock and clock□Respectively high level and during low level, if in is high level,
Then in□For low level, B1 and B2 are respectively low level, and C1 and C2 are respectively high level;(2) when clock and clock are respectively
When high level and low level, if in is low level, in□For high level, then B1 and B2 is high level, and C1 and C2 is low electricity
It is flat.It is the circuit conditions under clock and clock is respectively low level and high level to keep operation.
The present invention has the anti-SEU immunitys of single node, because the present invention has symmetry, and following section is worked as in only analysis
Anti- SEU characteristics when point A, B1, B2, C1, C2, D are respectively logic 1,0,0,1,1,0, make a concrete analysis of as follows.
The first situation:Node B1 is hit the transient pulse for occurring 0 → 1 by high energy particle.NMOS tube N1A is become by cut-off
To turn on, but because NMOS tube N1B still ends, so node A will not be overturn.On the other hand, even if B1 negative transient state
Pulse enables to N3A conductings and therefore pulling down node C1 logic level, but this can only allow NMOS tube N4A cut-offs to change
Become node D level, so node D floatings are in high-impedance state, Fig. 4 is circuit theory when node B1 of the invention is overturn
Schematic diagram.
Second of situation:Node B2 is hit the transient pulse for occurring 0 → 1 by high energy particle.NMOS tube N1B is become by cut-off
To turn on, but it is due to that NMOS tube N1A still ends, so node A will not be overturn.On the other hand, even if B2 negative wink
State pulse enables to N3B conductings and therefore pulling down node C2 logic level, but this can only allow NMOS tube N4B cut-offs can't
Concept transfer D level, so node D floatings are in high-impedance state, Fig. 5 is that circuit when node B2 of the invention is overturn is former
Manage schematic diagram.
The third situation:Node C1 is hit the transient pulse for occurring 1 → 0 by high energy particle.It is when node C1 is overturn from 1
When 0, NMOS tube N2A is changed into cut-off from turning on, so node B1 floatings but can't overturn.Likewise, NMOS tube N4A is by turning on
It is changed into cut-off, also only makes node D floatings, Fig. 6 is circuit theory schematic diagram when node C1 of the invention is overturn.
4th kind of situation:Node C2 is hit the transient pulse for occurring 1 → 0 by high energy particle.It is when node C2 is overturn by 1
When 0, NMOS tube N2B is changed into cut-off from turning on, so node B2 floatings but can't overturn.Likewise, NMOS tube N4B is by turning on
It is changed into cut-off, also makes node D floatings, Fig. 7 is circuit theory schematic diagram when node C2 of the invention is overturn.
5th kind of situation:Node A is hit the transient pulse for occurring 1 → 0 by high energy particle.If node A is by high energy
The strike of particle, the transient pulse for occurring 1 → 0, and PMOS P2A may be caused to turn on, but because node C1 makes for high level
NMOS tube N2A conductings are obtained, and NMOS tube N2A has the driving force higher than PMOS P2A, node B1 can't be overturn.Together
Sample, node B2 and node D will not also be overturn, and finish node A level recovers, and the node A that Fig. 8 is the present invention is overturn
When circuit theory schematic diagram.
6th kind of situation:Node D is hit the transient pulse for occurring 0 → 1 by high energy particle.If node D is by high energy grain
The strike of son, it is 1 that node D transient pulse is overturn by 0, only ends PMOS P3A, P3B, and cause node C1, node C2
Floating, can't produce level upset, and Fig. 9 is circuit theory schematic diagram when node D of the invention is overturn.
In summary, the upset of each redundant storage node is all without the upset for causing other any nodes, so that
Whole latch structure will not be overturn, and the present invention is a latch structure that there is single node SEU to be immunized, and the present invention is solved
The problem of anti-SEU.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these improve and deformed
Also it should be regarded as protection scope of the present invention.
