    • 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.
    • 提供了用于吹制和检测反熔丝的方法和装置。 具体地,在第一方面中,提供一种通过选择一组反熔丝中的一个并且施加高电压来改变所选择的反熔丝的状态来改变多个反熔丝之一的状态的方法。 在第二和第三方面中,提供了用于执行第一方面的方法的装置。 在第四方面,提供了一种用于升压电压的方法,包括以下步骤:在第一级升压电路的第一级存储机构内产生第一电压,产生等于第一级升压电路中第一电压的大约两倍的第二电压, 第二级升压电路的第二级第二级存储机构,并且基于第二级升压电路的第二电压产生约三倍的第一电压。 在第五方面中,提供了用于执行第四方面的方法的装置。
