  • Full rail drive enhancement to differential SEU hardening circuit
    Patent number: 6608512
    Abstract: A hardening circuit is provided for an integrated circuit which includes a data state reinforcing feedback path having a data node Q and a data complement node QN. A first hardening transistor is coupled between a rail and the data node Q, and a second hardening transistor coupled between the rail and the data complement node QN. The first and second hardening transistors provide additional drive to the data node Q and the data complement node QN. Gate controls operate the first and second hardening transistors and provide full rail drive to SEU sensitive nodes.
    Type: Grant
