An antifuse bank includes a bank of self-decoupling anti fuse circuits. The anti fuse circuits are programmed according to a pattern of address bits by blowing antifuses corresponding to bits of the address. The antifuses are blown by applying a high voltage across the antifuse. As each antifuse is blown, its resistance drops and current through the antifuse increases. The self-decoupling circuit detects the increased current flow and, when the anti fuse resistance is sufficiently low, limits current flow through the anti fuse. The antifuse thus does not load the high voltage source as other antifuses are blown.
