Semiconductor device and method for operating the same

A semiconductor device comprising:

• a first latch configured to be turned on according to first two clock signals so that input data received at the first latch is output as first output data;
• and
• a second latch configured to be turned on according to second two clock signals so that the first output data received at the second latch is output as second output data;
• wherein the second latch is configured to be turned on after a predetermined time delay after the first latch is turned off.

A method for operating a semiconductor device comprising:

• generating a first edge of a first clock from a first edge of a reference clock and disabling a first latch;
• generating a first edge of a second clock that does not overlap the first edge of the first clock from the first edge of the first clock and enabling a second latch;
• and
• generating a second edge of the first clock from a second edge of the reference clock and enabling the first latch, and generating a second edge of the second clock that overlaps the second edge of the first clock from the second edge of the reference clock and disabling the second latch.
