1. A system, comprising:
a control unit electrically connectable to an input of a memory via a communication interface;
where the control unit includes two power supply sectors: a first power supply sector configured to be powered when the control unit is in an operating mode and to be switched off when the control unit is in a low consumption mode, and a second power supply sector configured to be powered when the control unit is in the operating mode and powered when the control unit is in the low consumption mode;
wherein the control unit includes:
in the first power supply sector, a first configuration circuit operating when the control unit is in the operating mode to configure a polarization value of said input of the memory via the communication interface; and
in the second power supply sector, a second configuration circuit operating when the control unit is in the low consumption mode to configure the polarization value of said input of the memory via the communication interface.
