摘要： A signal transmission unit includes a first transmission line, a second transmission line, and a tapered transmission line coupling the first transmission line to the second transmission line. The tapered transmission line has a width and a length and the width changes along the length according to one or more functions. The one or more functions include but are not limited to linear functions, non-linear functions, hyperbolic functions, and exponential functions.

摘要： A method of self-refresh in a memory array includes initializing a programmable refresh counter of a memory module to an offset value from at least another memory module in the memory array. A data line carrying a system-wide self-refresh indicator signal is interrogated to determine whether any memory module is in a self-refresh mode. The self-refresh mode for the memory module is entered if the programmable refresh counter indicates that a self-refresh cycle is due, and it is determined that no other memory modules are in the self-refresh mode.
摘要翻译：存储器阵列中的自刷新方法包括将存储器模块的可编程刷新计数器初始化为来自存储器阵列中的至少另一个存储器模块的偏移值。询问携带全系统自刷新指示符信号的数据线，以确定任何存储器模块是否处于自刷新模式。如果可编程刷新计数器指示自刷新周期到期，并且确定没有其他存储器模块处于自刷新模式，则输入存储器模块的自刷新模式。

摘要： Briefly, in accordance with one embodiment of the invention, a system includes two boards coupled by a bus. The bus having a dual-terminated transmission line that communicatively couples a memory control hub with a memory repeater hub that each have a Rambus ASIC Cell (RAC). Briefly, in accordance with another embodiment of the invention, a connector has two metal traces that are of different lengths. The parasitic capacitance of the longer metal trace is increased so that the impedance of the two metal traces is substantially equal.
摘要翻译：简而言之，根据本发明的一个实施例，系统包括通过总线耦合的两个板。总线具有双端接传输线，其将存储器控制集线器与每个具有Rambus ASIC单元（RAC）的存储器中继器集线器通信地耦合。简而言之，根据本发明的另一个实施例，连接器具有不同长度的两个金属迹线。较长金属迹线的寄生电容增加，使得两个金属迹线的阻抗基本相等。
