A circuit that facilitates faster diagnosis of plurality of logic circuits connected in a scan chain is provided. In some implementations a method is provided. A second communications device determines one or more antenna weighting vectors and one or more bitloading vectors by using the first message in accordance with a predetermined rule and transmits a second message including information pertinent to the AWVs and the BLVs to the first communications device. Next, one of shifting elements engages locking the output. The hydrogen barrier comprises silicon rich silicon oxide or amorphous silicon, which can be used in combination with an aluminum oxide layer to inhibit diffusion of process-related hydrogen into the ferroelectric capacitor layer.
