A voltage booster stage (2) including a voltage booster circuit (10); a generating circuit (12) generating an enabling signal (LSP) enabling the voltage booster circuit; and a control circuit (14) controlling the generating circuit. The control circuit (14) receives a standby signal (ENB), and presents combinatorial logics (44-55) generating an operating mode signal (SPn) having a first value indicating a voltage boost operating mode, and a second value indicating a supply voltage operating mode. The generating circuit (12) receives the operating mode signal (SPn) and the standby signal (ENB), and generates the enabling signal (LSP) enabling the voltage booster circuit in the presence of the standby signal (ENB) and the first value of the operating mode signal (SPn). <IMAGE>
