  • MAGNETORESISTIVE RANDOM ACCESS MEMORY
    Publication number: 20240099154
    Abstract: A magnetoresistive random access memory (MRAM) device includes a first array region and a second array region on a substrate, a first magnetic tunneling junction (MTJ) on the first array region, a first top electrode on the first MTJ, a second MTJ on the second array region, and a second top electrode on the second MTJ. Preferably, the first top electrode and the second top electrode include different nitrogen to titanium (N/Ti) ratios.

  • Magnetoresistive random access memory structure
    Patent number: 11917923
    Abstract: A magnetoresistive random access memory (MRAM) structure, including a substrate and multiple MRAM cells on the substrate, wherein the MRAM cells are arranged in a memory region adjacent to a logic region. An ultra low-k (ULK) layer covers the MRAM cells, wherein the surface portion of ultra low-k layer is doped with fluorine, and dents are formed on the surface of ultra low-k layer at the boundaries between the memory region and the logic region.

  • Mobile wide area network IP translation configuration
    Patent number: 10419236
    Abstract: A method, system and non-transitory computer storage readable medium comprise operating a Wide Area Network (WAN) device according to a first Internet protocol (IP) translation mode of operation, changing an initial connectivity status between the WAN device and a WAN and transitioning from the first IP translation mode of operation to a second IP translation mode of operation that is different from the first IP translation mode of operation based on the change in the initial connectivity status.
