Abstract: The present disclosure relates to a semiconductor structure and a manufacturing method thereof. The semiconductor structure includes: a substrate; a transistor, including a control terminal, a first terminal, and a second terminal; a first magnetic memory structure, a bottom electrode of which is electrically connected to the first terminal of the transistor; a second magnetic memory structure, a top electrode of which is electrically connected to the first terminal of the transistor, the bottom electrode of the first magnetic memory structure is located in a same layer with a bottom electrode of the second magnetic memory structure; a first bit line, electrically connected to a top electrode of the first magnetic memory structure; a second bit line, electrically connected to the bottom electrode of the second magnetic memory structure; and a selection line, electrically connected to a second terminal of the transistor.

Abstract: An extrusion head (1) for molding a pole piece and a molding device comprising same, and a molding method and a preparation method therefor. The extrusion head (1) comprises an extrusion head (1) housing, and a through extrusion channel (6) is provided inside the extrusion head (1) housing in an extrusion direction; and the extrusion channel (6) is divided into a transition cavity (61) and a molding cavity (62) that are in sequential butt joint and communication in the extrusion direction, and the diameter of the annular surface of the inner wall of the transition cavity (61) is gradually reduced in the extrusion direction.

Abstract: Methods, apparatus and systems for establishing voice communication are provided herein. An exemplary method can be implemented by an electronic device. A request initiated by a user can be received. The request can include one of a voice-communication request, a voice-communication-invitation request, a temporary-voice-communication request, a temporary-voice-communication-invitation request, an exclusive-voice-communication request, and an exclusive-voice-communication-invitation request. According to the request, a voice-room number can be obtained from a first server or a second server, without using third-party communication software. The method further includes starting a voice client and entering a voice room directly using the voice client, according to the voice-room number.
