    Abstract: A read circuit for sensing a resistance state of a resistive switching device in a crosspoint array utilizes an equipotential preamplifier connected to a selected column line of the resistive switching device in the array. The equipotential preamplifier delivers a sense current while maintaining the selected column line at a reference voltage near a biasing voltage applied to unselected row lines of the array. The read circuit has a reference current source for generating a sense reference current, and a current comparator connected to evaluate the sense current delivered by the equipotential preamplifier against the sense reference current and generating an output signal indicative of the resistance state of the resistive switching device.

    Abstract: A flexible media magnetic printing system provides for data storage within flexible media imprinted with magnetic ink. In a particular embodiment, the printing system includes at least one reservoir of magnetic ink with magnetic particles capable of supporting high density data, and at least one reservoir of visible ink. The reservoirs are coupled to a print head including one or more ink-ejecting nozzles, which is removably or fixedly coupled to at least one magnetic read/write device. The magnetic read/write device tracks above the magnetic ink applied by the ink-ejecting nozzles to the flexible media. The magnetic read/write device writes to the magnetic ink by providing a magnetic field of sufficient intensity to re-orient the magnetic alignment within the ink to a known direction. The magnetic read/write device also reads data from flexible media, for example, paper or cloth that is imprinted with data-embedded magnetic ink. Visible or substantially invisible magnetic ink may be applied as dots within or strips beneath characters printed in visible ink. An inkjet printer head incorporating the flexible media magnetic printing system is further provided.

    Abstract: A system and method for determining the logic state of a memory cell in a magnetic tunnel junction (MTJ) memory device based on the ratio of the current through the cell at different bias points are disclosed. A memory cell in an MJT memory device is sequentially subjected to at least two different bias voltages. The current through the cell at each of the bias voltages is measured, and a ratio of the different currents is determined. The ratio is then compared with a predetermined value to determine the logic state of the cell. The predetermined value can be a known value. Alternatively, the predetermined value can be determined by application of the system and method to a reference cell having a known logic state.
