    Patent number: 9219409
    Abstract: A charge pump regulator includes a charge pump circuit, a voltage divider, a mode determining circuit, a frequency divider, and a selecting circuit. The charge pump circuit receives an oscillation signal and generates an output signal. The voltage divider receives the output signal and generates a first and a second divided voltages. The mode determining circuit determines whether the charge pump regulator is in a pumping mode or a detecting mode, and issues a first control signal. When the mode determining circuit is in the pumping mode, a pumping enable signal is activated and the clock signal is converted into the oscillation signal by the selecting circuit. When the mode determining circuit is in the detecting mode, a detecting enable signal is activated and the frequency divider generates a detecting signal according to the first control signal.

  • Top-down fabrication method for forming a nanowire transistor device
    Patent number: 9121820
    Abstract: The present disclosure relates to a top-down method of forming a nanowire structure extending between source and drain regions of a nanowire transistor device, and an associated apparatus. In some embodiments, the method provides a substrate having a device layer disposed over a first dielectric layer. The device layer has a source region and a drain region separated by a device material. The first dielectric layer has an embedded gate structure abutting the device layer. One or more masking layers are selectively formed over the device layer to define a nanowire structure. The device layer is then selectively etched according to the one or more masking layers to form a nanowire structure at a position between the source region and the drain region. By forming the nanowire structure through a masking and etch process, the nanowire structure is automatically connected to the source and drain regions.

  • Current sensing amplifier and sensing method thereof
    Patent number: 9099191
    Abstract: A sensing method of a current sensing amplifier is provided used for determining a storing state of a cell of a non-volatile memory device during a read cycle. After a sensing node and a reference node are adjusted to a constant voltage, the sensing node and the reference node are maintained in a floating state. Then, the sensing node is connected with a data line to receive a cell current from the cell, and the reference node is connected with a reference current source to receive a reference current from the reference current source. When a reference voltage of the reference node reaches a preset voltage, the storing state of the cell is determined according to a relationship between a sensing voltage of the sensing node and the preset voltage.
