<p>The invention relates to uncommitted logic arrays comprising semi-conductor structures in integrated circuit form and is concerned with the problems of access to elements of each cell, and packing density, Such a structure is described having an array of cells each of which comprises transistors which are not, or are only partially, interconnected. Some of the transistors have their electrode regions connected to externally accessible contact areas, The transistors are symmetrically arranged in each cell, and the cell may include an outer ring of contact regions which may be connected together in pairs by connecting links buried below an insulating substrate. The arrangement of each cell enables connections to be made to any pair of transistors even from the opposite corner of the cell, and gives good packing density,</p> |
