  • Publication number: 20060239225
    Abstract: A channel selecting method for a Wireless Local Area Network (WLAN) using remote scanning and a WLAN system thereof is disclosed in which a wireless environment is comprehensively discriminated to select an optimum channel by information. The information is obtained from stations of each node (STA) in a wireless network and is not local information near the Access Point. Channel selection is configured to be automatically implemented during an initial configuration of the WLAN and during operation. The method includes the AP requesting remote scanning for each node (STA) comprising the WLAN. Each node transmits a remote scanning result to the AP. An optimum channel is discriminated and a determination is made as to whether transfer has been made to the channel based on the information received from each node. The AP, transferring to the optimum channel, thus discriminated to form a new WLAN if channel transfer is implemented according to the discrimination.

  • Publication number: 20060055017
    Abstract: Embodiments of the invention include a stacked board-on-chip (BOC) package having a mirroring structure and a dual inline memory module (DIMM) on which the stacked BOC package is mounted. A bottom surface of a first semiconductor chip faces a bottom surface of a second semiconductor chip. An interposer electrically connects first and second packages, respectively comprising the first and second semiconductor chips, to each other. The DIMM is obtained by electrically connecting BOC packages to each other on upper and lower substrates of a printed circuit board. Since a height of the stacked BOC packages is greater than a height of a conventional stacked BOC package, the DIMM has a minimum stub length and an optimal topology. Hence, the DIMM can have a signal with excellent fidelity by reducing a load upon a signal line, and installation or wiring of components within the DIMM 300 requires less effort.

  • Publication number: 20060059298
    Abstract: A memory module includes a first set of at least one first type of memory device and a second set of at least one second type of memory device having a higher capacity than the first type. In addition, an additional capacity portion of the first and second sets stores information for an additional function of the memory module, and a remaining capacity portion of the first and second sets forms a rank of the memory module. The memory module avoids an asymmetric topology of signal lines and yet provides additional memory capacity.
