    摘要： Apparatus and methods are disclosed herein for a reverse-connection STT MTJ element of a MRAM to overcome the source degeneration effect when switching the magnetization of the MTJ element from the parallel to the anti-parallel direction. A memory cell of a MRAM having a reverse-connection MTJ element includes a switching device having a source, a gate, and a drain, and a reverse-connection MTJ device having a free layer, a fixed layer, and an insulator layer interposed between the free layer and the fixed layer. The free layer of the reverse-connection MTJ device is connected to the drain of the switching device and the fixed layer is connected to a bit line (BL). The reverse-connection MTJ device applies the lower IMTJ capability of the memory cell caused by the source degeneration effect to the less stringent IMTJ(AP->P) while preserving the higher IMTJ capability for the more demanding IMTJ(P->AP).

    摘要： Disclosed herein is an improved memory device, and related methods of manufacturing, 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.

    摘要： A method for projection correction includes following steps. An original image is projected as a projection image on an object. A projection-zone image including the projection image is captured from the object. A projection image outline corresponding to the projection image is obtained from the projection-zone image. An operation is performed on the projection image outline to obtain a horizontal inclination and a vertical inclination. The original image is pre-warped according to the horizontal inclination and the vertical inclination to obtain a corrected image, and the corrected image is projected on the object.

    摘要： The present disclosure provides a swinging device having a swinging mechanism disposed on an energy provider, wherein volume and shape of the swinging mechanism and a distance between the swinging mechanism and the energy provider are adjusted so as to control the ratio of the distance and a characteristic value corresponding to the swinging mechanism in a specific range such that the swinging mechanism is capable of resonating with respect to the rotation of the energy provider. The swinging mechanism is capable of detecting the rotating frequency of the energy provider as well as combining with a display unit which is capable of displaying information with respect to the rotating status or displaying image patterns controlled according to the rotating status.
