摘要:
A method and an eFuse circuit for implementing with enhanced eFuse blow operation without requiring a separate high current and high voltage supply to blow the eFuse, and a design structure on which the subject circuit resides are provided. The eFuse circuit includes an eFuse connected to a field effect transistor (FET) operatively controlled during a sense mode and a blow mode for sensing and blowing the eFuse. The eFuse circuit is placed over an independently voltage controlled silicon region. During a sense mode, the independently voltage controlled silicon region is grounded providing an increased threshold voltage of the FET. During a blow mode, the independently voltage controlled silicon region is charged to a voltage supply potential. The threshold voltage of the FET is reduced by the charged independently voltage controlled silicon region for providing enhanced FET blow function.
