IPC: A61B5/145
Filed: 2001-10-15
Abstract: A method and apparatus extract a signal component of a measured signal using one of two methods. If the signal component in the measured signal is a periodic signal with a certain well-defined peak-to-peak intensity value, upper and lower envelopes of the measured signal are determined and analyzed to extract said signal component of the measured signal. This signal component can further be used to calculate a desired parameter of the sample. The DC component of the signal is determined as the median value of the upper envelope, and the AC component is determined as the median value of the difference between the upper and lower envelopes. If the signal component of the measured signal is a periodic signal characterized by a specific asymmetric shape, a specific adaptive filtering is applied to the measured signal, resulting in the enhancement of the signal component relative to a noise component. This adaptive filtering is based on a derivative of the Gaussian Kernel having specific parameters matching the characteristics of the signal component.

IPC: H01L43/08

Abstract: An asymmetric cell and bit design for an MRAM device. The design is asymmetrical with respect to the easy-axis of the cell and has a centroid displaced from bit center along the hard-axis of the cell. This asymmetry is large enough so that manufacturing process variations do not substantially change the switching fields of the bits. In addition, the asymmetry causes the ends of the bits to align in opposite directions in small half-select fields and parallel to each other at large half-select fields, which increases the difference in the switching fields between selected and unselected bits. The combined effect of these two characteristics results in increased bit yield (relative to similarly sized symmetric bits) due to a smaller overlap between selected and unselected bit switching distributions.
