Memory device for base band-chip of mobile radio unit, has control unit controlling switch based on information stored in memory units, such that switch separates reading circuits from supply voltage

摘要

The device has a set of non-volatile memory units (211, 221, 231), and reading circuits (212, 222, 232) provided for reading memory information stored in the memory units. A switch (240) is provided for supplying the reading circuits with a supply voltage. A control unit (241) is connected between the reading circuits and a positive potential or a negative potential or both terminals of the supply voltage. The control unit controls the switch based on the information stored in the memory units, such that the switch separates the reading circuits from the supply voltage.. An independent claim is also included for a method for operating a memory device.
