ABSTRACT:
A semiconductor memory circuit having a controller by means of which the semiconductor memory circuit can be switched into a standby mode with a reduced power requirement, comprises an analog subcircuit having a power input and a signal output and is characterized by the fact that a switching device for feeding electrical power is connected to the power input and the controller is connected to the switching device in such a way that the switching device can be driven by the controller in such a way that the switching device, in the standby mode, supplies the analog subcircuit with electrical power during a first periodically repeated time duration and does not supply it with electrical power during a second periodically repeated time duration.
