ABSTRACT OF THE DISCLOSURE An extended logical scale structure of a programmable logic array includes a logic array part which carries out a logic operation provided by a logic circuit for an input signal and provides an output signal indicative of an operation result. The logic array part includes semiconductor switching elements provided at programmable logic array intersecting points, the logic operation of a logic circuit being changed by logic setting data supplied to the semiconductor switching elements. The structure further includes a storage circuit which stores a plurality of sets of logic setting data, and a switching circuit which sequentially selects one of the sets of logic setting data stored in the storage circuit and supplying the logic array part with the selected set of logic setting data.
