ABSTRACT:
A programmable logic array integrated circuit device has regions of programmable logic grouped in blocks disposed on the device in a two-dimensional array of intersecting rows and columns. Each block includes a relatively small number of logic regions to reduce the size and complexity of the local feedback circuity required in the block. Interconnection conductors extend along each row and column of blocks. Some of these conductors are segmented along their length to permit independent use of each segment. When longer interconnections are required, however, adjacent segments can be interconnected by programmable bi-directional switches between the segments.
