    摘要: An antifuse bank includes a bank of self-decoupling antifuse circuits. The antifuse 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 antifuse resistance is sufficiently low, limits current flow through the antifuse. The antifuse thus does not load the high voltage source as other antifuses are blown.
