Abstract: The circuit has a refresh controller (48) controlled by a clock signal, and another refresh controller operating during standby periods. A local oscillator (51) receives another clock signal whose frequency is lower than that of the former signal and corresponds to clock frequency of events of global system for mobile communication network. A voltage regulator (59) supplies a memory network during the standby periods. An independent claim is also included for a mobile phone including a mobile phone circuit with a dynamic memory comprising a control circuit.
