In an embodiment, a voltage converter is configured to operate by a succession of operating cycles, each cycle comprising an energy accumulation phase and an energy restitution phase, wherein the converter is further configured to determine a duration of one of the phases by comparing a voltage ramp and a first reference voltage, and wherein a slope of the voltage ramp depends on a sign of a current in an inductor at an end of a previous operating cycle.

A system includes a control unit configured to be electrically connected to an input of a memory via a communication interface. The control unit includes a first power supply sector configured to be powered when the control unit is in an operating mode and a second power supply sector configured to be powered when the control unit is in the operating mode and in a low consumption mode. In the first power supply sector, the control unit includes a first configuration circuit operating to configure a polarization value of the input of the memory via the communication interface for the operating mode. In the second power supply sector, the control unit includes a second configuration circuit operating to configure a polarization value of the input of the memory via the communication interface for the low consumption mode.
