Predictive power management

Abstract

Methods, systems, and devices for predictive power management are described. Correlations may be identified between a set of commands performed at the memory device and oscillating voltage patterns, or a resonance frequency, or both. Voltages may be monitored by the memory device and be compared to the identified voltage pattern to mitigate undesirable oscillating voltages and resonance frequency.
