Abstract
This document describes apparatuses and techniques for multi-rail power transition. In various aspects, a power rail controller transitions a memory circuit (e.g., of a memory die) from a first power rail to a second power rail. The power rail controller then changes a voltage of the first power rail from a first voltage to a second voltage. The power rail controller may also adjust termination impedance or a clock frequency of the memory circuit before transitioning the memory circuit to the second power rail. The power rail controller then transitions the memory circuit from the second power rail to the first power rail to enable operation of the memory circuit at the second voltage. By so doing, the power rail controller may improve the reliability of memory operations when transitioning operation of the memory circuit from the first voltage to the second voltage.
