The present invention discloses a method and an apparatus for triggering a status report in a RLC acknowledged mode protocol. The method includes turning the tool in the borehole. The driving unit applies a burst signal having a constant amplitude and a constant frequency between the gate electrode and the semiconductor layer and performs at least one of operations of programming and erasing charge on the charge retention layer. The second chamber includes a casting mold for casting a plurality of filaments of a superalloy composition. Because the memory function bodies are separated from each other by the gate electrode, interference during rewrite operation is effectively suppressed.
