For a component produced using integrated technology for providing integrated circuits with at least one programmable matrix shaped connecting field formed on a substrate with line and column conductors which can be connected in the area of at least one part of their intersecting points by coupling elements, two activatable or two deactivatable coupling elements (42,44) with a direction of activity at an angle of 90.degree. to one another are assigned to each of at least one part of the intersection points within the connecting field.

Component produced using integrated technology for the fabrication of

A logic array module, produced by integrated techniques for forming integrated circuits, encompasses a substrate on which are designed at least one linking field and outside of it active elements which serve for the input and output of signals and for expanding the scope of the linking field, and it is constructed of tracks (48, 56; 46, 54), arranged in the shape of columns and lines, which can be intercoupled on their crossing points (intersections) by activatable or deactivatable coupling elements (50, 58) that, depending on the status (state of connection) of a track, influence the status of a track that crosses the former so that logic linkages can be realized on the crossing track. In order to enable to form several logic linking planes within the same linking structure, the coupling elements (50, 58) of the linking field are arranged so that at least two linking matrices (44, 52) are formed with parallel lines (46; 54) and columns (48; 56) in parallel among them, where the lines (46; 54) and columns (48; 56) of the one linking matrix (44; 52) cross the columns (56; 48) and lines (54; 46) of the other linking matrix (52; 44). Furthermore, there is at least one track (46, 48; 54, 56) of a linking matrix (44; 52) connectable with at least one track (54, 56; 46, 48) of the other connecting matrix (52; 44) by means of a connecting element (62).

Programmable logic array having connectable matrices

An integrated circuit component, particularly a programmable logic array (PLA), includes at least one logic AND-array and a logic OR-array connected thereto. Some of the input lines of the PLA are sued to control the selection of output signals of the OR-array via a multiplexer thereby reducing the complexity and necessary programming of the PLA without a loss of flexibility.

Integrated circuit component

A programmable logic array chip is provided with an auxiliary grid pattern of conductive paths. Connecting elements can be selectively activated to connect certain ones of the auxiliary paths to the normal grid pattern paths which are connected to functional elements. In such manner, it is possible to provide a logic array chip that has increased flexibility in terms of user programmable functions.
