Abstract

A power management integrated circuit (PMIC) includes a voltage regulator, a monitoring circuit, and a count register. The voltage regulator is configured to generate an output voltage. The monitoringcircuit is configured to receive a feedback voltage of the output voltage, and to determine at each of periodic intervals whether the feedback voltage is outside a threshold voltage range. The countregister is configured to store a count value indicative of a number of times the feedback voltage is determined by the monitoring circuit to be outside the threshold voltage range.

Description

technical field [0001] Embodiments of the inventive concepts described herein relate to power management integrated circuits (PMICs), to memory modules and computing systems including PMICs, and to methods of operating memory systems including PMICs. Background technique [0002] Power management integrated circuits (PMICs) are mainly used to provide and distribute appropriate power supply voltages to various semiconductor devices included in the system. In particular, the PMIC can regulate the level of the supply voltage and / or the amount of current to be supplied to a given semiconductor device within the system. However, due to many factors including operating environment, operating state, working load, operating frequency, etc., the power integrity (PI) of the power supply voltage provided by the PMIC may be adversely affected. Contents of the invention [0003] According to an aspect of the inventive concept, there is provided a power management integrated circuit (P...
