Abstract
A semiconductor device includes an input/output (I/O) control signal generation circuit, a pipe circuit and an auto-pre-charge signal generation circuit. The I/O control signal generation circuit generates an input control signal, an output control signal and an internal output control signal. The pipe circuit latches an internal command/address signal based on the input control signal and outputs the latched internal command/address signal as a latch signal. The auto-pre-charge signal generation circuit generates an auto-pre-charge signal from the latch signal and the internal latch signal.
