Semiconductor devices including pipe latch units and system including the same

摘要

The semiconductor device includes a pre-signal generator and a data output portion. The pre-signal generator generates a pre-input control signal and a pre-output control signal. The pre-signal generator also generates a pre-latch pulse signal by detecting when the pre-input control signal and the pre-output control signal are generated. The data output portion receives an input control signal, a latch pulse signal, and a first output control signal. The data output portion receives an input clock signal in response to the input control signal and the latch pulse signal to generate a shift clock signal, and the data output portion also shifts the first output control signal in response to the shift clock signal to generate a second output control signal.

1. A semiconductor device comprising:
a latch pulse generator configured to generate a latch pulse signal by detecting when an input control signal and a first output control signal are generated; a clock latch controller configured to latch the input control signal in response to the latch pulse signal to generate a latch signal and configured to receive an internal clock signal in response to the latch signal to generate a shift clock signal; and an output control signal generator configured to shift the first output control signal to generate a second output control signal when the shift clock signal is generated.
