Abstract
Semiconductor devices are provided. One of the semiconductor devices may include a synthetic clock generator and a flag signal generator. The synthetic clock generator may be configured to generate a synthetic clock signal in response to a test enablement signal. The synthetic clock signal may be generated from a clock signal to include a first section pulse and a second section pulse having different pulse widths. The flag signal generator may be configured to latch a test signal in response to the synthetic clock signal to generate a flag signal.
Claims22
A semiconductor device comprising:
- a synthetic clock generator suitable for generating a synthetic clock signal in response to a test enablement signal, the synthetic clock signal being generated from a clock signal to include a first section pulse and a second section pulse;
- and
- a flag signal generator suitable for latching a test signal in response to the synthetic clock signal to generate a flag signal,
- wherein the first section pulse has a different pulse width than the second section pulse.
