Toy models of developed turbulence

A semiconductor logic device having arrays of logic elements and chains of logic cells alternately arranged in a direction substantially perpendicular to the direction of the chains of logic cells in a surface portion of a semiconductor substrate. Each of the logic element arrays has input and output leads extending from the array in the above-mentioned direction substantially perpendicular to the direction of the chains of logic cells so that each of said logic cell chains is in an electrical connection with two adjacent logic element arrays via the input and output leads.
