Abstract
A fuse circuit includes a control signal generation unit configured to generate a control signal that is enabled after a moment when a power-up signal is enabled, a potential control unit configured to control potentials of both ends of a fuse in response to the control signal, and a fuse output unit configured to be initialized in response to the power-up signal and output a fuse signal in response to whether the fuse is cut or not.
Claims14
A fuse circuit, comprising:
- a control signal generation unit configured to generate a control signal that is enabled after a moment when a power-up signal is enabled;
- a potential control unit configured to control potentials of both ends of a fuse in response to the control signal;
- and
- a fuse output unit configured to be initialized in response to the power-up signal and output a fuse signal in response to whether the fuse is cut or not.

A method for operating a fuse circuit, comprising:
- initializing a sense node where a value corresponding to whether a fuse is cut or not is detected in response to a power-up signal;
- driving the sense node by detecting whether the fuse is cut or not;
- outputting a fuse signal corresponding to whether the fuse is cut or not based on a logic level of the sense node;
- and
- controlling potentials of both ends of the fuse after the driving of the sense node.
