Abstract :
A CMOS-compatible zero-additional- mask one time programmable (OTP) non-volatile memory (NVM) for passive radio frequency identification (RFID) tags is presented. The selection of anti-fuse (AF) elements is discussed. The high voltage (HV) reliability issue for AF arrays is investigated and a high voltage switch drawing zero DC current is developed to tolerate the high voltages required for programming. Various AF memory cells and the HV switch were fabricated in standard TSMC 0.18 mum process. The breakdown of the AFs has been characterized and the functionality of the HV switch has been verified by measurement.
