Abstract
Such a device is disclosed that includes a terminal, a first voltage generator generating, when activated, a voltage at the terminal and stopping, when deactivated, generating the voltage, and a second voltage generator generating, when activated, the voltage at the terminal and stopping, when deactivated, generating the voltage. The first voltage generator being configured to be activated in response to a first control signal taking an active level and deactivated in response to the first control signal taking an inactive level, and the second voltage generator being configured to be activated in response to each of the first control signal and a second control signal taking an active level and deactivated in response to at least one of the first and second control signal taking an inactive level.
