Abstract
The invention provides an electrical fuse device comprising: a plurality of fuse cores, each having an electrical fuse element and a switching element serially connected to the electrical fuse element; a program control circuit generating a program shift signal by sequentially shifting a program control transmission signal in synchronization with an effective program clock signal and subsequently generating a program signal to be sent to each of the switching elements in the plurality of fuse cores based on program data and the program shift signal; and a program clock control circuit controlling the conducting and non-conducting states of a program clock signal in accordance with a program clock enable signal and, when the program clock signal is in a conducting state, transmitting the program clock signal to the program control circuit as the effective program clock signal.
