  • Patent number: 10452113
    Abstract: A programmable-threshold power supply selector has two power-supply inputs VDD1 and VDD2. The higher of these two voltages is pre-selected as a common supply that powers all transistors and circuitry in the programmable-threshold power supply selector, including substrates under transistors. An open-loop decision circuit is very stable since it uses no feedback. A tunable voltage divider divides VDD1 by a programmable divisor. The divided VDD1 is compared to a reference voltage to generate switch-control signals. The switch-control signals drive the gates of p-channel switch transistors that connect either VDD1 or VDD2 to an output supply voltage. The different programmable divisor values effectively cause VDD1 to be compared to a programmable threshold voltage VTH. The switch transistors switch the output supply voltage to VDD2 only when VDD1 falls below VTH. The output supply voltage remains at VDD1 even when VDD1 falls below VDD2, eliminating unnecessary power switching.

  • Publication number: 20190305217
    Abstract: Embodiments of the disclosure provide methods for forming MTJ structures from a film stack disposed on a substrate for MRAM applications and associated MTJ devices. The methods described herein include forming the film properties of material layers from the film stack to create a film stack with a sufficiently high perpendicular magnetic anisotropy (PMA). An iron containing oxide capping layer is utilized to generate the desirable PMA. By utilizing an iron containing oxide capping layer, thickness of the capping layer can be more finely controlled and reliance on boron at the interface of the magnetic storage layer and the capping layer is reduced.
