Provided is an organic electro-luminescence display device. The coupling electrode is adjacent to a word line in a NAND string and has a voltage applied which reduces gate induced drain lowering program disturb of an adjacent unselected non-volatile storage element. The current-compensated choke includes a first winding and a second winding, wherein a first current flowing from the rectifier to the inverter flows through the first winding and a second current flowing back from the inverter to the rectifier flows through the second winding. Access to the medical data stored on the computer readable medium is restricted, allowing the physician involved with the medical procedure to subsequently retrieve the medical data stored in the computer readable medium and view the medical data retrieved. The method further comprises associating a level of trust with the digital certificate based on the parameter of the cryptographic token.
