Abstract: 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).

Abstract: The present disclosure uses different kinds of surface treatment processes on titanium-made dental implants. The growth and attachment conditions of bone cells (MC3T3-E), fibroblasts (NIH 3T3) and epidermal cells (XB-2) on the metal surface of titanium slices with different surface treatments are observed. Tetra-calcium phosphate is used to perform secondary sand-blasting process to clean up the metal surface and provide calcium ions for osteoblastoma physiology. Thus, by adjusting the cells adhesive and proliferative abilities, the success rate of the clinical applications in dental implant is improved.
