Abstract

See full text

An e-fuse device includes a transferring circuit, a detecting-and-outputting circuit, and a fusing circuit. The transferring circuit transfers an input signal to a data node. The detecting-and-outputting circuit generates an output signal according to the logic level of the data node. The fusing circuit includes an e-fuse cell, a first transistor, a second transistor, and a switch element. The e-fuse cell is coupled between a high-voltage node supplied with the high voltage or a ground and a first node. The first transistor is coupled between the first node and a second node and is controlled by the output signal. The second transistor is coupled between the second node and the ground and is controlled by a fusing signal. The switch element is coupled between the first node and the data node and is controlled by a switch signal.
