摘要： The present invention refers to a field emitter beam source (10) comprising at least one emitter (11); at least one extracting electrode (19) to extract a beam current (IE) from the emitter (11); a current source (12) for providing a predetermined beam current (IE0); a first voltage source (13) for providing a first voltage (UA) between the emitter (11) and the extracting electrode (19) to switch on the beam current (IE); and a first switch (S1) for disconnecting the first voltage source (13). With such a field emitter beam source, the emitter voltage (UE) necessary to emit a predetermined beam current (IE0) can be determined. This in turn enables the field emitter beam source (10) to generate beam current pulses with a fast rise time and a well defined beam current pulse charge Q.

摘要： A method for improving read signals in a memory including passive memory elements provided at crossover locations of word and bit lines, and in which stored digital information is represented by a respective resistance of the memory elements includes: determining logic levels of information bits to be written to the memory elements associated with a respective bit line; inverting the logic levels of the information bits if more than half of information bits to be written to the memory elements associated with the respective bit line have a logic level corresponding to a low-value resistance of the memory elements; writing the information bits to the memory elements; and generating an additional check bit, a logic level of which represents an inverted or non-inverted state of the information bits.
