Abstract: A processing device performs dual-rail power equalization for its memory cell array and logic circuitry. The memory cell array is coupled to a first power rail through a first switch to receive a first voltage level. The logic circuitry is coupled to a second power rail through a second switch to receive a second voltage level that is different from the first voltage level. The processing device also includes a power switch coupled to at least the second power rail and operative to be enabled to equalize voltage supplied to the memory cell array and the logic circuitry.

Abstract: A portable device is provided. A first processor performs an initial procedure according to an operation clock with a first frequency value and an operation voltage with a first voltage value, and performs a calibration procedure according to the operation clock with a second frequency value and the operation voltage with a second voltage value when the initial procedure has been performed and a self-calibration event is present. A second processor detects whether a specific function of the calibration procedure is being performed by the first processor. The second processor stores the second frequency value and the second voltage value into a storage unit after the calibration procedure is performed. The second voltage value is lower than the first voltage value, and the second frequency value is lower than the first frequency value.
