Abstract: Provided is a memory device, comprising a non-volatile memory, an energy store coupled to an input power module of the non-volatile memory, and a power management module configurable to determine whether or not to supply backup power to the non-volatile memory via the energy store to initiate a shutdown process, based on differentiating a voltage glitch from an actual loss of power in a power line. Provided also is a computational device that includes the memory device. Provided also is a method in which a power management module of the memory device determines whether or not to supply backup power to the non-volatile memory via the energy store to initiate a shutdown process, based on differentiating a voltage glitch from an actual loss of power in a power line.

Abstract: Power management circuitry initiates storage of backup energy in an energy storage resource. The backup energy is stored to power an electronic circuitry during a power failure condition in which primary power is unavailable to power the electronic circuit. During a test mode, the power management circuitry selectively discharges the backup energy stored in the energy storage resource at multiple different energy discharge rates to test the energy storage resource.
