APPARAT ZUR VERBESSERUNG DES GEGENSICHERUNGS- PROGRAMMIERERTRAGS UND ZUR REDUKTION DER GEGENSICHERUNGS-PROGRAMMIERZEIT

摘要

The present invention includes four approaches to reduce the unintended programming of antifuses while programming selected antifuses and to decrease the programming time. The first approach includes circuitry to maintain the voltage placed on unselected antifuses at a constant level by use of a voltage source. According to the second approach, a resistor is included in series with the voltage source. According to the third approach, a diode is included in series with the voltage source. According to the fourth approach, a MOS implementation of a diode is included in series with the voltage source.
