Abstract:
Data transmission system and method are provided. The transmission system includes a data converter and data restoring unit. The data converter converts N-bit first data to be transmitted into M-bit second data, where M is greater than N and the second data is arranged in a minimum unit greater than 1, each minimum unit including at least successive data bits having the same phase. The transmitter compresses the second data prior to transmission via a channel having performance characteristics defining a minimum pulse width, and a receiver receives and de-compresses the transmitted second data. The data restoring unit then restores the first data from the second.
Abstract:
A semiconductor device, a method related to the semiconductor device, and a printed circuit board are disclosed. The semiconductor device includes a chip, a package including a plurality of power voltage terminals and a plurality of ground voltage terminals, wherein the chip is disposed in the package. The semiconductor device further includes an impedance circuit connected between a DC component power voltage terminal and a ground voltage, wherein the DC component power voltage terminal is one of the plurality of power voltage terminals, and an AC component interrupter connected between the DC component power voltage terminal and a power voltage. Both the AC component and a DC component of the power voltage are applied to each of the power voltage terminals except the DC component second power voltage terminal, and the ground voltage is applied to each of the ground voltage terminals.

Abstract:
A system board includes a control unit; connectors arranged in series in one direction and accepting a connecting means for inputting and outputting data; and signal lines connecting the control unit to the connectors and including at least one branch point, wherein sub signal lines branched off at the same branch point are equal in length and/or loads of path from the branch point to the connecting means.
Abstract:
A memory system includes a memory controller, a memory bus connected to the memory controller, and a plurality of memory modules connected along the memory bus, where each of the memory modules includes a plurality of memory devices. The system also includes a dummy stub or a dummy module connected to the memory bus between the memory controller and the memory module closest to the memory controller among the plurality of memory modules. The dummy stub or dummy module improves a signal integrity of at least the memory module closest to the memory controller.
Abstract:
A system and method for providing access to a unified message store logically storing computer telephony messages is disclosed. A multiplicity of heterogeneous storage objects corresponding to computer telephony messages are stored in a unified message store. An application software layer exchanging the heterogeneous storage objects with a computer telephony server is exported. The computer telephony server is interfaced via a container subsystem defining encapsulated methods including organization strategy methods and storage strategy methods. A unified inbox generating an indicator for at least one of the computer telephony messages is provided. The unified inbox exports user controls for accessing the corresponding heterogeneous storage objects stored in the unified message store.
