Abstract
A semiconductor device includes a plurality of first output terminals-and a plurality of first output circuitsprovided corresponding to each of the plurality of first output terminals and coupled to a corresponding first output terminal. The semiconductor device further includes a second output circuitcoupled to a second output terminal DQS. The second output circuit automatically adjusts a slew rate based on the state transitions of the plurality of first output circuits. The second output circuit adjusts the slew rate from a first state to a second state based on a transition from first data outputted from the first output circuit to second data following said first data. The second output circuit outputs data in synchronization with the second data with a slew rate in said second state.
