In a row decoder (10'), an input node receives a row selection signal (ln_lv) and an output node (11) is coupled to a word line (WL) of a memory. A pull-down circuit (12a) is coupled between the output node and ground and selectively couples the output node to ground when the row selection signal is asserted. A pull-up circuit (14) is coupled between the output node and a supply node (15) that provides a selectable supply voltage (shifted_supply), and selectively couples the output node to the supply node when a deselection signal (Vcomm) is de-asserted. An inverter (16) is supplied between the supply node and a shifted ground node that provides a selectable ground voltage (shifted_gnd), receives as input a control signal (V₁) from a control node (18), and produces the deselection signal. A current generator (19) sources a biasing current (I₁) to the control node. A further pull-down circuit (12b') is coupled between the control node and ground, and selectively couples the control node to ground when the row selection signal is asserted.

A voltage-regulator (50) provides regulated-voltage to a digital circuit (60) from a supply-voltage input (VDD). The regulator (50) includes an amplifier (51) comparing a reference-voltage (Vbg) with the regulated-voltage to control a source-gate voltage of an output-transistor (MP1).

The boosting-circuit includes a capacitor (C) switchable connected between the supply-voltage (VDD) and either a bias current source (IB3) or the gate of the output-transistor (MP1). A phase-generator (57) controls two switches (S1, S2) through non-overlapping control-signals (φint, φsh), implementing an integration-phase and a sharing-phase. During integration, the capacitor (C) charges to a voltage above the source-to-gate voltage of the output-transistor (MP1). During sharing, this charged capacitor (C) connects to the gate of the transistor (MP1), boosting the source-to-gate voltage to increase current sourcing capability during high-frequency digital circuit operation. A clock-gating circuit (55) enables the phase-generator (57) in response to clock activation, synchronizing the boost operation with periods of increased current demand.
