Moore's Law
? Moore, Gordon E. (1965). "Cramming more components onto integrated circuits" (PDF). Electronics Magazine. pp. 4.
? "The complexity for minimum component costs has increased at a rate of roughly a factor of two per year."
? Moore refined it to "every two years" in 1975 ? Also quoted as "every 18 months" by David House, (referring to
performance) ? Most popular formulation: #transistors/IC
? Carver Mead coined it as Moore's law around 1970
? "Tall & Thin engineers"
? Ultimate limit of Moore's Law
? No one knows ? How to use the capability? Resource limit?
