Abstract

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.
