  • Patent number: 9184586
    Abstract: Some embodiments of the present disclosure relate to a low-power, area efficient ESD protection device that provides ESD protection to an ESD susceptible circuit. The ESD protection device has a trigger circuit with a resistor. The resistor has a first terminal connected to the first external pin and a second terminal connected directly to a gate of a SiGe based PMOS shunt transistor. The trigger circuit generates a trigger signal that drives the gate of the PMOS device to shunt power away from the ESD susceptible circuit when an ESD event is present. The SiGe based PMOS shunt transistor has a lower gate leakage than a conventional NMOS shunt transistors, thereby providing for an ESD circuit with a low leakage current at small gate lengths.

  • Patent number: 8207755
    Abstract: A leakage current reduction circuit comprising a transmission gate, a feedback channel and a controller is placed between a first device supplied with a first voltage potential and a second device supplied with a second voltage potential. The voltage potential mismatch between the first device and the second device may cause a leakage current flowing through the input stage of the second device. By employing the low leakage power detection circuit, a logic high state generated from the first device can be converted into a logic high state having an amplitude approximately equal to the second voltage potential.

  • Patent number: 7923286
    Abstract: A phase-change memory comprises a bottom electrode formed on a substrate. A first isolation layer is formed on the bottom electrode. A top electrode is formed on the isolation layer. A first phase-change material is formed in the first isolation layer, wherein the top electrode and the bottom electrode are electrically connected via the first phase-change material. Since the phase-change material can have a diameter less than the resolution limit of the photolithography process, an operating current for a state conversion of the phase-change material pattern may be reduced so as to decrease a power dissipation of the phase-change memory device.

  • Patent number: 7868314
    Abstract: A phase change memory device and fabricating method are provided. A disk-shaped phase change layer is buried within the insulating material. A center via and ring via are formed by a lithography. The center via is located in the center of the phase change layer and passes through the phase change layer, and the ring via takes the center via as a center. A heating electrode within the center via performs Joule heating of the phase change layer, and the contact area between the phase change layer and the heating electrode is reduced by controlling the thickness of the phase change layer. Furthermore, a second electrode within the ring via dissipates the heat transmitted to the contact interface between the phase change layers, so as to avoid transmitting the heat to the etching boundary at the periphery of the phase change layer.
