Technologies are generally described for selectively charging a capacitor coupled to a memory. Example electronic devices described herein may include a memory; a capacitor coupled to the memory; a power supply configured to supply power at least to the capacitor; a switch coupled between the power supply and the capacitor; and a switch controller coupled to the switch and configured to: determine whether the electronic device is in a safety mode or in a normal mode, and control an operation of the switch, based on the determination. So, the supply of the power from the power supply to the capacitor is selectively controlled. |
