1. An apparatus, comprising:
a high logic level driver coupled to a data terminal and configured to be provided a first voltage, the high logic level driver configured to provide a high logic level voltage to the data terminal when activated;
a low logic level driver coupled to the data terminal and configured to be provided a second voltage, the low logic level driver configured to provide a low logic level voltage to the data terminal when activated; and
an intermediate logic level driver coupled to the data terminal and configured to be provided a third voltage having a magnitude that is between the first and second voltages, the intermediate logic level driver configured to provide an intermediate logic level voltage to the data terminal when activated,
wherein each of the high logic level driver, the low logic level driver, and the intermediate logic level driver are configured to be respectively activated based on one or more of a plurality of control signals, wherein the intermediate logic level driver comprises:
a pull-up middle driver configured to provide the intermediate logic level voltage to the data terminal when activated; and
a pull-down middle driver configured to provide the intermediate logic level voltage to the data terminal when activated,
wherein the pull-up middle driver and the pull-down middle driver are further configured to be concurrently activated.
