Claim:
1. A sense structure comprising: a plurality of sense amplifiers, each comprising biasing circuitry configured to provide a biasing voltage to the biasing terminal of the plurality of sense amplifiers; common regulating circuitry configured to regulate the biasing voltage for the plurality of sense amplifiers and comprising a voltage reference terminal configured to receive a reference voltage; each sense amplifier further comprising local regulating circuitry configured to regulate the biasing voltage applied to the biasing terminal, the local regulating circuitry comprising a local capacitor and a resistor coupled in series, the local capacitor coupled to the biasing terminal and the resistor coupled to the voltage reference terminal; a first transistor selectively controllable and configured to couple the local regulating circuitry of each of the plurality of sense amplifiers to the common regulating circuitry to refresh the local regulating circuitry in a rest condition and to decouple the local regulating circuitry of each of the plurality of sense amplifiers from the common regulating circuitry in an operative condition; and each sense amplifier comprising a second transistor having first and second conduction terminals coupled to the reference terminal and the measuring terminal, respectively, and a gate terminal coupled to control circuitry, said second transistor configured to selectively couple the reference terminal to the measuring terminal during a pre-charging phase of the measuring terminal based upon a control signal received at the gate terminal from the control circuitry.
