Patent attributes
The present disclosure provides a method for determining status of a fuse element of a memory device. The method includes providing the memory device including a first terminal and a second terminal and applying a first power signal on the first terminal of the semiconductor device. The memory device includes a configurable reference resistor unit electrically coupled to the fuse element. The method also includes obtaining an evaluation signal at the second terminal of the memory device and identifying the evaluation signal to determine whether the memory device is redundant. The configurable reference resistor unit includes a first resistor, a first transistor connected in parallel with the first resistor, and a first configurable unit connected to a gate of the first transistor. The first configurable unit is configured to generate a first configurable signal to turn on the first transistor.
