Abstract
A semiconductor device may include a division control circuit and a latch circuit. The division control circuit may be configured to divide an external clock to generate a first preliminary divided clock and a second preliminary divided clock. The division control circuit may be configured to output the first and second preliminary divided clocks or any one of the first and second preliminary divided clocks as first and second divided clocks. The latch circuit may be configured to latch an external control signal in response to the first and second divided clocks and configured to output latched signals as first and second latch control signals.
Claims20
A semiconductor device comprising:
- a division control circuit configured to divide an external clock to generate a first preliminary divided clock and a second preliminary divided clock and configured to output the first and second preliminary divided clocks or any one of the first and second preliminary divided clocks as first and second divided clocks;
- and
- a latch circuit configured to latch an external control signal in response to the first and second divided clocks and configured to output first and second latch signals.
A semiconductor system comprising:
- an external device configured to provide an external control signal and an external clock;
- and
- a semiconductor device configured to divide the external clock to generate a plurality of divided clocks, and configured to latch the external control signal using the divided clocks or any one of the divided clocks.
