Abstract
The invention relates to a memory device comprising a non-volatile memory element, a read-out circuit for reading out an item of memory information stored in the memory element, a switching unit, by means of which a supply voltage can be applied to the read-out circuit, and a control unit, which has the capability of controlling the switching unit in a manner dependent on the memory information stored in the memory element.
Claims27
A memory device, comprising:
- at least one non-volatile memory element;
- a read-out circuit for reading out an item of memory information stored in the at least one memory element;
- a switching unit operable to apply a supply voltage to the read-out circuit;
- and
- a control unit, configured to control the switching unit in a manner dependent on the memory information stored in the at least one memory element.
A method for operating a memory device having at least one non-volatile memory element and a read-out circuit for reading out an item of memory information stored in the at least one memory element, the method comprising:
- (a) reading out of the memory information stored in the at least one memory element;
- and
- (b) dependent on the memory information stored in the at least one memory element:
- isolating the read-out circuit from a supply voltage;
- and
- applying the supply voltage to the read-out circuit.
