365158, 365194, 36518905, 36523311

Abstract:

A method for generating a variable pulse width signal on an integrated circuit (IC) chip, includes receiving a first clock signal on the IC chip and receiving a second clock signal on the IC chip having a variable delay relative to the first clock signal. A signal having a rising edge triggered by a rising edge of the first clock signal and a falling edge triggered by a rising edge of the second clock signal is output. The output signal is provided to circuitry on the chip, such as a magnetoresistive junction (MTJ) cell of a spin torque transfer magnetic random access memory (STT-MRAM).

US Classification:

438696, 438694, 438723, 438770, 438771

Abstract:

A method of forming spacers from a non-silicon oxide, silicon containing spacer layer with horizontal surfaces and sidewall surfaces over a substrate is provided. A plasma oxidation treatment is provided to form a silicon oxide coating over the spacer layer, wherein the silicon oxide coating provides a horizontal coating on the horizontal surfaces and sidewall coatings on the sidewall surfaces of the spacer layer. An anisotropic main etch that selectively etches horizontal surfaces of the spacer layer and silicon oxide coating with respect to sidewall surfaces of the spacer layer and the sidewall coatings of the silicon oxide coating is provided. The spacer layer is etched, wherein the sidewall coatings of the silicon oxide coating protect sidewall surfaces of the spacer layer.

Abstract:

Devices, systems and methods facilitate analyzing, identifying and sorting particles in fluids, including cytometry devices and techniques. The described techniques can be used in a variety of applications such as in chemical or biological testing and diagnostic measurements. One exemplary flow cytometry device includes a channel that is capable of conducting a fluid containing at least one particle and also capable of allowing light be transmitted to and from the channel. The flow cytometry device also includes a lens that is positioned between the channel and a color filter. The lens directs at least a portion of light transmitted from the channel to the color filter. The color filter includes a plurality of zones, where each zone is adapted to allow transmission of only a particular spectral range of light. The flow cytometry device further includes a detector configured to receive the light that is transmitted through the color filter.

International Classification:

G06F 132
G06F 1200

US Classification:

713320

Abstract:

A method and apparatus for indicating when a device in a computer system is communicating with memory. Information is communicated between the device and memory in a manner that bypasses a bus. A side-band signal that indicates that this communication is transpiring is sent to a second device connected to the second bus. In response to this side-band signal, a bit in a register of the second device is set to a value that is then communicated by way of the second bus.
