A semiconductor device includes a first amplifier circuit, a second amplifier circuit, first and second bit lines coupled to the first amplifier circuit, third and fourth bit lines coupled to the second amplifier circuit, a first equalizer circuit being coupled to the first and second bit lines, and a second equalizer circuit being coupled between the second and third bit lines. The inner ring is secured to the seat, while the outer ring is secured to the sear. The information received can be associated with a session corresponding to each widget instance andor with multiple identifiers, such as widget, user, content, session, content aggregation point, processor, andor placement identifiers, for example. The second amplifier circuit is disposed in a second signal path between a second input node and a second output node of the amplifier, and arranged to amplify a second input signal received at the second input node and accordingly generate a second amplified signal to the second output node.
