ABSTRACT:
A method and system is disclosed for protecting electrical fuse circuitry. A electrical fuse circuit with electrostatic discharge (ESD) protection has at least one electrical fuse, a programming device coupled in series with the electrical fuse having at least a transistor for receiving a control signal for controlling a programming current flowing through the electrical fuse, a voltage source coupled to the fuse and the programming device for providing the programming current, and a protection module coupled to a gate of the transistor at its first end for reducing charges accumulated at the gate of the transistor due to electric static charges arriving at the voltage source, thereby preventing the programming device from accidentally programming the fuse.
