  • Patent number: 8547006
    Abstract: A multi-beam electron gun provides a plurality N of cathode assemblies comprising a cathode, anode, and focus electrode, each cathode assembly having a local cathode axis and also a central cathode point defined by the intersection of the local cathode axis with the emitting surface of the cathode. Each cathode is arranged with its central point positioned in a plane orthogonal to a device central axis, with each cathode central point an equal distance from the device axis and with an included angle of 360/N between each cathode central point.

  • Patent number: 6477103
    Abstract: A reprogrammable fuse has a pair of non-volatile memory cells differentially programmed. The pair of non-volatile memory cells are connected to a pair of bitlines and through a pair of switches to a precharging voltage. The switches are controlled by a precharging and equalization signal, which when activated, serves to precharge the bitlines. The charged bitlines are then connected to the pair of differentially programmed non-volatile memory cells and one of the bitlines is discharged faster than the other. The resultant output is taken from one of the bitlines.
