Abstract: An apparatus is described. The apparatus includes a power management integrated circuit (PMIC) semiconductor chip having logic circuitry to implement a PMIC/PMIC interface having a downstream signal line and an upstream signal line. The downstream signal line to communicate any of multiple states that a downstream PMIC semiconductor chip is to implement with one of multiple voltage levels, where, different ones of the multiple voltage levels correspond to different ones of the multiple states. The upstream signal line is to communicate whether or not the downstream PMIC semiconductor chip is ready to receive a next one of the multiple voltage levels.

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: These present disclosure provides techniques to determine the capacitance of a power loss capacitor based on voltage ripple. The power loss capacitor may be a power loss capacitor for a power loss shutdown system of a solid state drive. The capacitance may be determined as a function of the voltage ripple and a period of the voltage ripple during a natural discharge and a controlled discharge of the power loss capacitor.
