Field programmable gate array having internal logic transistors with two different gate insulator thicknesses
 In a programmable device employing antifuses, first digital logic transistors the gates of which will experience a programming voltage Vpp have a greater gate insulator thickness than do second digital logic transistors the gates of which will not experience the programming voltage. The first digital logic transistors may be logic module input device transistors. The first digital logic transistors may be transistors coupled to an enable input lead where the enable input lead is couplable to a tie-high conductor or to a tie-low conductor depending on which of two antifuses is programmed.
