  • Publication number: 20190199834
    Abstract: The present disclosure provides a method, an apparatus and a terminal device for communication protocol compatibility. The method includes: receiving an external protocol list transmitted by an external device and retrieving a locally stored local protocol list; taking one of a same version information of the external protocol list and the local protocol list as matched version information, if the external protocol list and the local protocol list have the same version information; and taking the local protocol corresponding to the snatched version information as the protocol for communicating with the external device, and transmitting the matched version information to the external device. As a result, when the terminal device and the external device have the same communication protocol, they can perform data exchange using the same communication protocol automatically, which reduces the possibility of the incompatibility in the communication protocol so as to improve the communication success rate.

  • Patent number: 8546896
    Abstract: A method and system for providing a magnetic substructure usable in a magnetic device, as well as a magnetic element and memory using the substructure are described. The magnetic substructure includes a plurality of ferromagnetic layers and a plurality of nonmagnetic layers. The plurality of ferromagnetic layers are interleaved with the plurality of nonmagnetic layers. The plurality of ferromagnetic layers are immiscible with and chemically stable with respect to the plurality of nonmagnetic layers. The plurality of ferromagnetic layers are substantially free of a magnetically dead layer-producing interaction with the plurality of nonmagnetic layers. Further, the plurality of nonmagnetic layers induce a perpendicular anisotropy in the plurality of ferromagnetic layers. The magnetic substructure is configured to be switchable between a plurality of stable magnetic states when a write current is passed through the magnetic substructure.
