Abstract

A power management apparatus is provided. The 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 isconfigured 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.

Description

[0001] [Cross-reference to related applications] [0002] This application claims the rights of Korean Patent Application No. 10-2017-0161005 filed at the Korean Intellectual Property Office on November 28, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to a power supply device, and more particularly, to a secondary power supply device that supplies power secondarily and a storage system including the same. Background technique [0004] Generally, a storage system including a storage device and a storage controller operates by receiving power from an external source. In this regard, a sudden power off (SPO) situation may occur in which a power supply (eg, main / primary power supply) is suddenly discontinued while the storage system is operating. In such a situation, since the memory controller may utilize the volatile memory to store data, there may be a risk of loss of data stored in...
