A novel programming architecture for antifuse FPGA(Field Programmable Gate Array) is described. This architecture prevents programming transistors from breakdown which occurs due to high voltage across the transistors during antifuse programming. Extra mask and processes can be avoided using this proposed architecture. To reduce the applied voltage across the terminals of programming transistors, different voltage ranges are supplied to vertical and horizontal tracks; between programming voltage Vp and Vp/2 for vertical tracks and between Vp/2 and 0V for horizontal tracks. Therefore, Maximum voltage across the programming transistors is half of the programming voltage and an designated antifuse can be programmed by applying maximum voltage for vertical track and minimum voltage for horizontal track while others are subjected to voltage difference below Vp/2.
