A memory system of a high-speed operation can be realized by reducing an influence of reflection signals etc. caused by branching and impedance mismatching in various wirings between a memory controller and a memory module, and an influence due to transmission delays of data, command / address, and clocks in the memory module. To this end, a memory system comprises a memory controller and a memory module mounted with DRAMs. A buffer is mounted on the memory module. The buffer and the memory controller are connected to each other via data wiring, command / address wiring, and clock wiring. The DRAMs and the buffer on the memory module are connected to each other via internal data wiring, internal command / address wiring, and internal cock wiring. The data wiring, the command / address wiring, and the clock wiring may be connected to buffers of other memory modules in cascade. Between the DRAMs and the buffer on the memory module, high-speed data transmission is implemented using data phase signals synchronous with clocks.

The invention provides a service-oriented large-scale network security situational assessment device and method. The device comprises a monitoring platform and an acquisition agent, wherein the monitoring platform comprises a data analysis / index extraction module, a situational assessment module, a database middleware module, a command configuration module, a plug-in module and an XML (Extensible Markup Language) data conversion module; the acquisition agent comprises a server performance state acquisition agent, a network equipment state acquisition agent and a specific service performance state acquisition agent; the monitoring platform sends out an alarm in one or more modes and carries out emergency response by using a predefined event processing program; and the acquisition agent takes charge of receiving a specific monitoring command transmitted by the monitoring platform to finish acquisition of various network security situational indexes. The device and the method contribute to making accurate assessment on global security of a network system, facilitate timely adjustment of a security policy by a network administrator, and provide theoretical basis and technical support for subsequent security situational prediction and situational visualization.
