Abstract
A switch arrangement for switching a node between three supply voltages based on two control signals. The switch arrangement includes three circuits for connecting an output node with one of three nodes, each of which is set to a different voltage. The switch arrangement is controlled by six control signals that establish mutually exclusive switching modes and avoid combinational currents. The switch arrangement is also designed to allow the use of MOS transistors having a low nominal voltage, with a value that is lower than the highest voltage to be switched. The switch arrangement is particularly adapted to supply power to non-volatile memory cells.
