other 34 u 34 leads and each of the 34 l 34 leads also may be connected to each of the other 34 l 34 leads to program the programmable device 18 for example to assure that the lead 1u is connected only to lead 4l then except for the circuit connection 53 including fuse 54 all of the circuit connections and fuses for example including the circuit connection 55 and fuse 56 connecting to the lead 1u would be overloaded electrically to blow the respective fuses opening the respective circuit connections since the circuit connection 53 still would remain whole with the fuse 54 intact the result would be a connection to the lead 1u to the lead 4l via the circuit connection 53 and appropriate portions of the electrical lines 51 52 depending on which of the circuit connections are so open circuited the lead 1u may be connected to more than one other lead moreover by providing appropriate isolation paths and connection paths a lead designated with the suffix 34 u 34 may be connected to another lead designated by the suffix 34 u 34 and the same is true for leads with suffixes designated 34 l 34 it will be appreciated that although the array 50 in the programmable device 18 is described in detail herein with reference to the blowing or burning out of a fused link or circuit connection for example by overloading the same other.
