Rafael C Camarota, Frederick C Furtek, Walford W Ho, Edward H Browder: Programmable logic cell and array. Concurrent Logic, Pennie & Edmonds, September 1, 1992: US05144166 (334 worldwide citation)

A programmable logic array comprising cells and a bus network in which the cells are arranged in a two-dimensional matrix of rows and columns and are interconnected by the bus network. The cells are also interconnected by a two-dimensional array of direct connections between a cell and its four near ...
