Abstract

Apparatuses and methods for pre-emphasis control are described. An example apparatus includes a pull-up circuit and a pull-down circuit. The pull-up circuit is configured to receive a pull-up data activation signal and drive a data terminal to a pull-up voltage responsive to an active pull-up data activation signal. The pull-down circuit is configured to receive a pull-down activation signal and drive a data terminal to a pull-down voltage responsive to an active pull-down data activation signal. The example apparatus further includes a pre-emphasis circuit that includes a pre-emphasis timing control circuit configured to provide a timing control signal, and further includes a logic circuit. A pre-emphasis control signal based on at least one of the pull-up and pull-down data activation signals is provided to control providing pre-emphasis having a timing based on a mode of operation.
