    摘要: Disclosed are apparatus and methods for efficiently writing states to one or more magneto-resistive elements. In one embodiment, current switches are provided for directing a write current through a number of write lines to control the write state of the magneto-resistive elements. In another embodiment, a sense current is selectively controlled to control which magneto-resistive elements are written to a particular state. In both embodiments, a latching element may be used to sense the state of the magneto-resistive elements, and may assume a corresponding logic state.

    摘要: An optical transceiver having an integrated optical time domain reflectometer monitoring unit and methods for using the same are disclosed. The disclosure relates to an optical transceiver comprising an optical device comprising a wavelength division multiplexing system (WDM), a data signal driver, a data signal limiting amplifier, and an optical time domain reflectometer (OTDR) data processing module. Furthermore, the optical transceiver is particularly advantageous in an optical line terminal (OLT) and/or a passive optical network (PON). The integrated OTDR data processing module can protect the optical transceiver, ensure successful monitoring data, simplify network wiring and decrease system and network costs by decreasing the number of OTDR modules and WDM units.

    摘要: Method and apparatus for transferring data in a memory. A semiconductor memory includes a plurality of memory cells each having a resistive sense element (RSE) in series with a switching device. A conductive word line extends in a first direction adjacent the memory cells and is connected to a gate structure of each of the switching devices. A plurality of conductive bit lines extend in a second direction adjacent the memory cells, each bit line providing a connection node that interconnects a respective pair of the memory cells. A control circuit senses a programmed state of a selected memory cell by setting each of the bit lines on a first side of the selected memory cell to a first voltage level, setting each of the remaining bit lines on an opposing second side of the selected memory cell to a second voltage level, and setting the word line to a third voltage level.
