ABSTRACT:
The parallel antifuse scheme may be applied to a field programmable gate array architecture (10) having a logic module (16) with an output coupled to an output track (34, 54, 114, 144, 178, 198) coupled via a cross antifuse (38, 58, 116, 184, 208) to an connecting track (36, 56, 64, 118, 154, 182, 205, 206). The connecting track is further coupled via at least one cross antifuse (44, 46, 72, 74, 120, 122, 160, 162, 190, 218, 220) to at least one input track (40, 42, 68, 70, 188, 214, 216) coupled to an input of at least one logic module. The circuit includes a compensation track (124, 150, 180, 200) running generally in parallel with the output track and at least one parallel antifuse (125, 158, 186, 212) programmably coupling the compensation track (124, 150, 180, 200) and the connecting track. One or more controllable switch (130, 152, 174, 176, 194, 196), such as a pass transistor, is coupled between the output track and the compensation track.
