    摘要: Using a damascene process, a cup-shaped MTJ device is formed in an opening within a dielectric layer. A passivation layer is formed on the top surfaces of the sidewalls of the cup-shaped MTJ device to enclose the top of the sidewalls, thereby reducing magnetic flux leakage. Accordingly, the MTJ device may be fabricated using the same equipment that are compatible with and commonly used in CMOS technologies/processes.

    摘要: The invention discloses a MRAM (Magnetoresistive RAM) based on vertical current writing and its control method, the operation of information writing in the MRAM unit is completed by the corporate effect of the magnetic field generated by the current parallel to the MFC unit and the other current vertical to the MFC unit and passing through this unit. The advantage of such structure is: eliminating a word line (WL) of the prior art especially for information writing, reducing the number of the metal wiring layers and the contact holes, and reducing the complexity of MRAM's structure, and difficulty and cost of manufacturing process.
