] Moore's Law, as chip manufacturers generally refer to it

] Resolving these issues is a major goal for the entire

] number of transistors on a given chip every two years,
] an exponential growth pattern that has allowed computers
] to get both cheaper and more powerful at the same time.

Moore's law hits a wall at about 2021, when fundamental physics prevent devices from becoming any smaller. After that it will
be ncessary to take other steps (larger chips, 3D chips?) to continue the performance increase.
