A high-voltage switching circuit comprising: a switch having ON and OFF states and having a parasitic gate capacitance and a control circuit for turning the switch on and off. The method comprises assigning a configuration change of node role attributes to a node in the cluster, with each attribute being represented by a bit of a binary value. Magnetic Random Access Memory devices may include arrays of these memory cells. Once it is known when two optical surfaces to be glued are said to have zero gap, the present system provides an annunciation from limit-sensing electronics.
