ABSTRACT:
A programming circuit for an anti-fuse utilizes a boot circuit that charges a capacitor to the supply voltage during a non-programming period. Anti-fuse is to be programmed, the plate of the capacitor to which the supply voltage has been applied is switched to 0 volts, thereby causing the other plate of the capacitor to output a negative voltage. This negative voltage is switched to one plate of an anti-fuse, and the other plate of the anti-fuse receives a positive voltage from an external source. A voltage is thereby applied across the anti-fuse that is greater than any voltage applied to any node of the integrated circuit.
