Memory card with non-volatile memory

Memory card - a non-volatile memory (1200) and - a power management unit (1400) for providing an operating voltage (VDD) for the nonvolatile storage of a received external supply voltage (VEXT), - wherein the power management unit (1400) lifts the external supply voltage (VEXT), and the raised voltage as an operating voltage (VDD) for the non-volatile memory (1200) when the external supply voltage is lower than a predetermined detection voltage (V - wherein the power management unit (1400) provides a to a desired operating voltage limiting regulated voltage as the operating voltage for the nonvolatile memory, when the external supply voltage is higher than the desired operating voltage.
