An excellent book about cosmic ray threats to microcircuits In the braces passages of the decades, we have seen a dramatic
increase in the density of the active elements on the integrated
circuits of memory and logic. The volume and loads is associates to
you with a memory or the logic tip has been reduced therefore. But
there is a problem: to a sure point, a single cosmic beam can act as
from marks them launch one heads. And that point gives along time is
caught up for the cosmic beams of the heavyone. Fortunately, the
devices you on the surface of the earth are protect from the
atmosphere from the greater part of these, except protons of
less-dangerous. However, that anchor puts the integrated circuits
space-borne to the risk, therefore like the integrated circuits on
earth that are susceptible of protons. The 25 slid years or more,
these vibrations of the tip have demanded "single-event cuff" or
simply "SEUs." This book extension like analyzing to the problems
these cosmic beams presents. It is an excellent handbook, with the
bonds insiemi of the problems to the conclusion of every understood it
(and of the answers to the extremity of the book). The book begins
with a sure important preliminary material on continuous change, the
fluence, the density of current and the cross-sectional sections,
therefore like some important fundamental principles on the functions
of distribution of the rope. Those distributions of the rope come in
practical when the energy particles wished to know how much deposit in
the SEU-sensitive region. After it will be understanding it
approximately the enemy: nature, the distribution and the continuous
change of induction particles extraterrestrial. After that one, there
is an argument on the amount of warehouse of energy for the length of
the track of the unit, that it leads to one explanation of the
transfer of linear energy (LASCI). That one leads to the introduction
of a fundamental concept in the calculations of error-rate SEU, the
curve of Heinrich, from which extension the distribution of cosmic
beams LASCI. Moreover the reader perceives approximately the
disposition of the too much confidence on this curve: The
cross-sectional sections of SEU can vary with the type of the ione,
Ionian to high energy they are more dangerous than those to low
energy, even if both have the same one LEAVE, the energy lost from a
particle cannot all enter to in the near SEU-sensitive region, are
variances in the amount of deposited energy here, additional energy
can be pull to you in the sensitive region "pouring," and it can here
need of being corrections in order to overflow of cosmic beam. After
that one he comes understanding it on like verifying the devices
simply you to SEU predisposition, using the accelerators which
Brookhaven or exposing them to Californium-252. These tests observe
not only the vibrations of the tip, but also "latchup," that it can
damage permanent a device if is left fed over. After is one argument
detailed on the rates SEU (and the techniques for the computazione
they) for one atmosphere wide variety of the particle: heights
geosynchronous, the strap of Allen of van, neutrons to the heights
cruising of the aircraft, the Atlantic anomaly of the south and sea
level. Well, than what it must be made approximately all these
problems? The authors rifiniscono discussing the protection, the
circuit-hardening, the overabundance, to fregare, the survey of errors
and the correction of error in order to reduce or the errors of
against tip. That one demands one argument on the upsets of the
multiple-tip pure. That is a book much profit for that it must be
taken care of such problems, particularly in the design of the systems
space-borne.
