    Abstract: The present disclosure provides a 1S1R memory integrated structure and a method for fabricating the same, wherein the 1S1R memory integrated structure includes: a word line metal, a resistive material layer, a selector lower electrode, a selector material layer, a selector upper electrode, an interconnection wire, and a bit line metal; wherein the selector material layer is in a shape of a groove, and the selector upper electrode is formed in the groove. According to the 1S1R memory integrated structure and its fabricating method in the present disclosure, by the change of the integrated position of the selector, the device area of the selector is much larger than the device area of the memory, which significantly reduces the requirement for the on-state current density of the selector.

  • Publication number: 20200133217
    Abstract: A control method includes sending, by a controller, a created context-aware model to a context-aware engine. The context-aware model is used to define a preset control performed when target data meets a trigger condition and to instruct the context-aware engine to send indication information to the controller when the context-aware engine determines that the target data meets the trigger condition. The preset control is used to implement a context-aware function. The indication information is used to indicate that the target data meets the trigger condition. The method also includes receiving, by the controller, the indication information. The method further includes performing, by the controller, the preset control based on the indication information.
