Abstract:
Power management apparatuses are provided. A power management apparatus includes a secondary power device that includes at least one capacitor. The power management apparatus includes a charging circuit that includes a direct current (DC)-DC converter and that is configured to supply power to the secondary power device. Moreover, the power management apparatus includes a measuring circuit that is configured to measure a switching profile of the DC-DC converter, and to determine a state of the secondary power device by comparing at least one time period of the switching profile with a reference time. Related memory systems and methods of operation are also provided.
