Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for a fuse programming integrated circuit in which fuses are used in common by redundant elements. SOLUTION: A method and a device for initializing an integrated circuit by the use of the compressed data from a remote fuse box are capable of reducing fuses in number required for repairing or customizing the integrated circuit, and grouping the fuses outside macros which are repaired by the fuses. The remote position of the fuses improves the arrangement of the macros, having redundant repairing performances in flexibility and enables the fuses to be properly grouped for facilitating the usability of programming and the layout of circuits. The fuses are formed into columns and rows, to represent control words and run-length compressed data and to provide more repairing points per fuse. The data are loaded into a shift register in series and shifted to macro positions, for controlling the selection of redundant circuits, so that defective integrated circuits can be repaired, and the logic is customized.

Abstract: The circuit includes a static logic array implementing a predetermined logic function, having at least two inputs and two output lives, coupled by product term lines. A member of pull-down devices connect selected input and output lines to product term lines according to function implemented in the array. Output lines have pull-up device associated with them for pulling the voltage of output lines if no pull-down device connected is activated. Also product form pull-up devices for each line pull-ups the voltage of product from line positive if not pull-down device conencted to such line is activated. A switch arrangement provided, associated with each of product term pull-up devices selectively activates such devices or alternately applies a pull-down signal to the associated product product form line. A decoder provided implements a second predetermined logic function, so as to activate the product term pull-up devices operating an value applied to input lines.
