1. A correlation detector comprising:

  • an input unit configured to receive a plurality of parallel data streams of discrete events;

    a memory array comprising a plurality of resistive memory elements, wherein at least one of the resistive memory elements is allocated to each of the data streams;

    a programming array comprising a plurality of programming elements, wherein at least one of the programming elements is allocated to each resistive memory element for applying a programming signal to the respective memory element;

    a control unit configured to control the programming signals as a function of a co-arrival characteristic of the discrete events;

    a correlation unit configured to detect correlations between the data streams based on resistance changes of the resistive memory elements.
