Abstract: A field programmable gate array architecture comprises a plurality of horizontal and vertical routing channels each including a plurality of interconnect conductors. Some interconnect conductors are segmented by user-programmable interconnect elements, and some horizontal and vertical interconnect conductors are connectable by user-programmable interconnect elements located at selected intersections between them. An array of rows and columns of logic function modules each having at least one input and one output is superimposed on the routing channels. The inputs and outputs of the logic function modules are connectable to ones of the interconnect conductors in either or both of the horizontal and vertical routing channels. At least one column of random access memory blocks is disposed in the array.
