1. A method for decrementing a reference count in a multicast environment, comprising:

  • receiving an access request for a particle stored in a memory element, wherein the particle includes a plurality of data segments, a selected one or more of the data segments including a reference count;

    accessing the memory element in response to the access request;

    reading the particle from the memory element;

    presenting the particle to a target that generated the access request;

    decrementing the first reference count associated with the selected one or more of the data segments in order to generate a second reference count;

    writing at least one of the plurality of the data segments with the second reference count to the memory element; and

    preventing access to an address associated with the particle until the data segment with the second reference count is written to the memory element.
