Abstract:
A decoupling circuit and a semiconductor device including the same are provided. The decoupling circuit includes a first circuit including a first capacitor having a first end connected to a first terminal, a first switch device connected between a second end of the first capacitor and a second terminal, and a first control device configured to turn on/off the first switch device based on a voltage level of the a second end of the first capacitor, and a second circuit including a second capacitor having a first end connected to the first terminal, a second switch device connected between a second end of the second capacitor and the second terminal, and a second control device configured to turn on/off the second switch device based on a voltage level of the second end of the second capacitor and an output signal of the first control device.
Abstract:
A repair circuit includes first and second fuse circuits, a determination circuit and an output circuit. The first fuse circuit includes a first fuse and is configured to generate a first master signal indicating whether the first fuse has been programmed. The second fuse circuit includes second fuses and is configured to generate a first address indicating whether each of the second fuses has been programmed. The determination circuit is configured to generate a detection signal based on the first master signal and the first address. The detection signal indicates whether a negative program operation has been performed on the second fuse circuit. The output circuit is configured to generate a second master signal based on the first master signal and the detection signal and generate a repair address corresponding to a defective input address based on the first address and the detection signal.
