Methods and apparatus for blowing and sensing antifuses are provided. Specifically, in a first aspect, a method is provided for changing the state of one of a plurality of antifuses by selecting one of the bank of antifuses and applying a high voltage to change the state of the selected antifuse. In second and third aspects, apparatus are provided for performing the method of the first aspect. In a fourth aspect, a method is provided for boosting a voltage that includes the steps of generating a first voltage within a first stage storage mechanism of a first stage voltage booster circuit, generating a second voltage equaling about twice the first voltage within a first and a second, second stage storage mechanism of a second stage voltage booster circuit, and generating about thrice the first voltage based on the second voltage of the second stage voltage booster circuit. In a fifth aspect, apparatus are provided for performing the method of the fourth aspect.
