Abstract
Data storage device has a super-capacitor, a control unit with multiple operational states, non-volatile memory, and a bus connected to a computing device with a separate power source. The control unit state is set by the power level of the computing device and the super-capacitor. In a backup state, the control unit stores backup data from the computing device in the non-volatile memory using power from the super-capacitor. In an inactive state, the control unit does not receive power from the super-capacitor. The control unit is set to the backup state when the device power level is less than a first threshold and the super-capacitor voltage level is greater than a second threshold. The control unit is set to the inactive state when the super-capacitor voltage level decreases below a third threshold that is less than the second threshold by more than the dielectric absorption voltage gain of the super-capacitor.
