<p>A method for programming antifuses is described. Programming current pulses are driven through a selected antifuse (11). The resistance through the antifuse is then measured (13) and compared (14) to a predetermined resistance value. These measuring, comparing and driving steps are repeated until the measured resistance is less than a predetermined resistance value and the antifuse is annealed by driving a predetermined amount of current through the antifuse for a first predetermined amount of time and ramping down (16) the current in a predetermined manner in a second predetermined amount of time. With this programming method no complex methods and circuits to reverse the polarities of voltage across and currents through the antifuse are required.</p> |
