    摘要: An RC-based sensing scheme to effectively sense the cell resistance of a programmed Phase Change Material (PCM) memory cell. The sensing scheme ensures the same physical configuration of each cell (after programming): same amorphous volume, same trap density/distribution, etc. The sensing scheme is based on a metric: the RC based sense amplifier implements two trigger points. The measured time interval between these two points is used as the metric to determine whether the programmed cell state, e.g., resistance, is programmed into desired value. The RC-based sensing scheme is embedded into an iterative PCM cell programming technique to ensure a tight distribution of resistance at each level after programming; and ensure the probability of level aliasing is very small, leading to less problematic drift.

    摘要: Nearby conductors such as pipes, well casing, etc., are detectable from within a borehole filled with an oil-based fluid. At least some method embodiments provide a current flow between axially-spaced conductive bridges on a drillstring. The current flow disperses into the surrounding formation and causes a secondary current flow in the nearby conductor. The magnetic field from the secondary current flow can be detected using one or more azimuthally-sensitive antennas. Direction and distance estimates are obtainable from the azimuthally-sensitive measurements, and can be used as the basis for steering the drillstring relative to the distant conductor. Possible techniques for providing current flow in the drillstring include imposing a voltage across an insulated gap or using a toroid around the drillstring to induce the current flow.
