    Abstract: An embodiment of the invention includes a memory cell having a magnet layer coupled to a metal layer and read line. The metal layer is also coupled to write and sense lines. During a write operation charge current is supplied to the metal layer via the write line and induces spin current and a magnetic state within the magnet layer based on the spin Hall effect. During a read operation read current is supplied, via the read line, to the magnet layer and then the metal layer and induces another spin current, within the metal layer, that generates an electric field and voltage, based on inverse spin Hall effect, at a sense node coupled to the sense line. The voltage polarity is based on the aforementioned magnetic state. The memory operates with a low supply voltage to drive charge, read, and spin currents. Other embodiments are described herein.

    Abstract: In general, in one aspect, an apparatus includes a phase frequency detector, a charge pump, a voltage controlled oscillator, an integral capacitor to maintain an integral charge and provide an integral voltage, and a mutual-charge canceling sample reset (MCSR) capacitor to maintain a proportional charge and provide a proportional voltage each reference clock cycle. The MCSR includes a first proportional capacitor, a second proportional capacitor in parallel to, and having substantially identical capacitance value as, the first proportional capacitor, a first set of switches to provide direct coupling of the first and second proportional capacitors, and a second set of switches to provide cross coupling of the first and second proportional capacitors. The first and second set of switches alternatively turn on and off every reference clock cycle so that set of switches coupling the first and second proportional capacitors alternates every reference clock cycle.

    Abstract: The present invention provides a mechanism for adjusting the activity of an integrated digital circuit such as a processor to reduce voltage changes attributable to current changes triggered by clock gating. The processor includes one or more functional units and a current control circuit that monitors activity states of the processor's functional units to estimate the current consumed over n clock cycles. The current control circuit estimates the current change for a given clock cycle from the n activity states and compares the estimated current change with first and second thresholds. The processors activity is decreased if the estimated current change is greater than the first threshold, and the processor activity is decreased if the estimated current change is less than the second threshold.
