  • Patent number: 7990734
    Abstract: A semiconductor memory module having a reverse mounted chip resistor, and a method of fabricating the same are provided. By reverse mounting the chip resistor on the semiconductor memory module, the resistive material is protected, thereby preventing open circuits caused by damage to the resistive material. Also, a chip-resistor connection pad of a module substrate is formed to extend higher from the module substrate than other connection pads connected to other elements. Thus, the resistive material of the chip resistor does not contact the module substrate, thereby preventing poor alignment and defective connections.

  • Publication number: 20090193463
    Abstract: A method and system for sharing information between users while reproducing media in a media reproducing system, the method including: reproducing the media in the media reproducing system; capturing a part of the media in the media reproducing system; and registering a media related question including the captured part of the media in an information sharing server through a return channel of the media reproducing system. Accordingly, the users can share information in real time by generating the media related question by directly capturing the media in the media reproducing system, registering the media related question in the information sharing server, and displaying on the media reproducing system of another user that such media related question is registered. Also, since a question can be directly registered while reproducing the media, information can be conveniently shared without interrupting the media reproduction.
