    Abstract: Disclosed herein is an improved memory device wherein the area occupied by a conventional landing pad is significantly reduced to around 50% to 10% of the area occupied by conventional landing pads. This is accomplished by removing the landing pad from the cell structure, and instead forming a conductive via structure that provides the electrical connection from the memory stack or device in the structure to an under-metal layer. By forming only this via structure, rather than separate vias formed on either side of a landing pad, the overall width occupied by the connective via structure from the memory stack to an under-metal layer is substantially reduced, and thus the via structure and under-metal layer may be formed closer to the memory stack (or conductors associated with the stack) so as to reduce the overall width of the cell structure.

    Abstract: An optical lens module includes a support frame, a liquid crystal lens group, and a aberration compensation lens group. The aberration compensation lens compensates aberrations generated by the liquid crystal lenses. The liquid crystal lens group and the fixed aberration compensation lens group are disposed on the same optical axis. The optical lens module is power-saving, easily assembling, and has a small volume, which is helpful for miniaturizing and thinning optical lens modules, and thus further helpful for miniaturizing and thinning small-size or portable devices.

    Abstract: An apparatus and methods for a non-volatile magnetic random access memory (MRAM) device that includes a word line, a bit line, and a magnetic thin film memory element located at an intersection of the word and bit lines. The magnetic thin film memory element includes an alloy of a rare earth element and a transition metal element. The word line is operable to heat the magnetic thin film memory element when a heating current is applied. Heating of the magnetic thin film memory element to a predetermined temperature reduces its coercivity, which allows switching of the magnetic state upon application of a magnetic field. The magnetic state of the thin film element can be determined in accordance with principles of the Hall effect.
