Advantageously, use of high-energy barrier magnets (30-40KT where K is the Boltzmann constant and T is the operating temperature) not only allows compact stochastic primitives, but also enables the same device to be used as a stable memory element meeting the data retention requirement.
The new definitions will be based on fixed numerical values of the Planck constant (h), the elementary charge (e), the Boltzmann constant (k), and the Avogadro constant (NA), respectively.
[sigma] is the Boltzmann constant, [[euro].sub.j] is the emissivity of element j, Ti is the temperature of the source i, [T.sub.j] is the temperature of element j, [N.sub.S] is the number of surfaces interacting with j, and [t.sub.r] is the time for a single revolution.
