Abstract
A delay adjusting apparatus may include at least one selective delay element electrically coupled to an electrical path between an input terminal and an output terminal of the electrical path, and the at least one selective delay element configured to add a delay factor to the electrical path in response to an enable signal. The delay adjusting apparatus may include at least one fuse circuit configured to control electrical coupling of an e-fuse, in response to a program signal, and program the enable signal.
Claims16
A delay adjusting apparatus comprising:
- at least one selective delay element electrically coupled to an electrical path between an input terminal and an output terminal of the electrical path, and the at least one selective delay element configured to control electrical coupling of an electrical delay element to the electrical path in response to a logic state of an enable signal;
- and
- at least one fuse circuit configured to control electrical coupling of an e-fuse, in response to a program signal, and program the enable signal.
An operating apparatus comprising:
- at least one delay adjusting apparatus configured to control electrical coupling of an e-fuse, based on a program signal, and program an enable signal, and adjust a delay time of an input signal in response to the programmed enable signal and output an output signal;
- and
- a program control circuit configured to generate the program signal to adjust the delay time,
- wherein the delay adjusting apparatus comprises:
- at least one selective delay element electrically coupled to an electrical path electrically coupled between the input signal and the output signal of the at least one delay adjusting apparatus, and configured to control electrical coupling of an electrical delay element to the electrical path in response to a logic state of the enable signal;
- and
- at least one fuse circuit configured to control electrical coupling of the e-fuse, in response to the program signal, and program the enable signal.
