Abstract
An integrated circuit includes a high voltage generator generating a high voltage, a negative voltage generator generating a negative voltage, a divided voltage generator generating a divided voltage by dividing the power source voltage and supplying it to a read voltage terminal, a first power gate supplying the high voltage or the divided voltage to a program voltage terminal, a second power gate supplying the negative voltage or the ground voltage to a deactivation voltage terminal, a third power gate supplying the ground voltage or the divided voltage to an activation voltage terminal, and an e-fuse array circuit operating using voltage of the program voltage terminal as a program voltage, voltage of the divided voltage terminal as a read voltage, voltage of the activation voltage terminal as an activation voltage, and voltage of the deactivation voltage terminal as a deactivation voltage.
