    Abstract: A method for generating a prompt message for network connection conversion and a network system thereof are provided. The system can be a LAN with multiple access points (APs). The method is operated in a root AP. The root AP receives a connection conversion command from a user device, in which a target AP is designated. The root AP determines at least one AP that is available to be connected with the target AP based on an instant wireless signal strength there-between. After that, the target AP obtains at least one connection rates from the target AP to the root AP via the at least one available APs. The root AP generates a prompt message for connection conversion according to the connection rates. A topology map displayed on the user device can be used to indicate the available APs for the connection conversion.

  • Patent number: 10608174
    Abstract: Double-patterned magneto-resistive random access memory (MRAM) for reducing magnetic tunnel junction (MTJ) pitch for increased MRAM bit cell density is disclosed. In one aspect, to fabricate MTJs in an MRAM array with reduced MTJ row pitch, a first patterning process is performed to provide separation areas in an MTJ layer between what will become rows of fabricated MTJs, which facilitates MTJs in a given row sharing a common bottom electrode. This reduces the etch depth and etching time needed to etch the individual MTJs in a subsequent step, can reduce lateral projections of sidewalls of the MTJs, thereby relaxing the pitch between adjacent MTJs, and may allow an initial MTJ hard mask layer to be reduced in height. A subsequent second patterning process is performed to fabricate individual MTJs. Additional separation areas are etched between free layers of adjacent MTJs in a given row to fabricate the individual MTJs.
