Apparatus for stabilizing an antifuse used for a memory device
 An antifuse stabilizing apparatus for a memory device stabilizes a programming process of an antifuse. A serial antifuse block has a plurality of antifuses being interconnected in series, and is programmed by applying a voltage being higher than an appropriate applying voltage of each antifuse. An antifuse programming block applies a program voltage being higher than the appropriate applying voltage to both ends of each antifuse in order to program the antifuses. A high voltage portion and a low voltage portion check a coupling state of the antifuses of the serial antifuse block. The applying voltage higher than the appropriate applying voltage is a voltage to be applied to both ends of each antifuse by the antifuse programming block. As a result, all circuits of using an antifuse whose appropriate applying voltage is lower than a power-supply voltage of the peripheral circuit can use the antifuse stably without using an additional circuit.
