Abstract
Disclosed is an integrated electronic circuit comprising a core circuit that generates a useful signal as well as a buffer for storing the useful signal. The buffer stores the last read value of the useful signal for a predetermined period of time when the power supply is interrupted, and the buffer is disconnected from the power supply of the other circuits.
Claims5
An integrated electronic circuit that receives a supply voltage VDD, comprising:
- a measurement circuit that provides a measured signal;
- and
- an intermediate memory for storing the measured signal, wherein, upon a disturbance in the supply voltage VDD the intermediate memory retains the latest measured signal for a predetermined period, and wherein the intermediate memory is decoupled from the supply voltage VDD,
- wherein the intermediate memory stores the measured signal value until it is ensured that valid values of the measured signal value are again read-in to the intermediate memory.
