Abstract: An apparatus includes a hit bitline driver circuit and an equalization control circuit. The hit bitline driver circuit may be configured to drive a pair of hit bitlines responsive to a search bit. The equalization control circuit may be configured to transfer charge from one hit bitline of the pair to the other hit bitline of the pair in response to the search bit changing state.

Abstract: An integrated circuit output buffer includes a core terminal, a pad terminal, a pad pull-up transistor, a pad pull-down transistor, a pull-up voltage protection transistor, and a selectively conductive pad voltage feedback path. The pad pull-up transistor and the pad pull-down transistor are coupled to the pad terminal and are biased to respectively charge and discharge the pad terminal in response to a data signal received on the core terminal. The pull-up voltage protection transistor is coupled in series between the pad pull-up transistor and the pad terminal and has a control terminal and a well terminal. The selectively conductive pad voltage feedback path is coupled between the pad terminal and the well terminal of the pull-up voltage protection transistor.
