There are four different busses, with each classified by its function—a “memory bus” in this organization is actually composed of separate (1) data, (2) address, (3) control, and (4) chip-select busses. Each of these busses is dedicated to handle only its designated function, except in a few instances, for example, when control information is sent over an otherwise unused address bus wire.(1) The data bus is relatively wide: in modern PC systems, it is 64 bits wide, and it can be much wider in high-performance systems. (2) The width of the address bus grows with the number of bits stored in an individual DRAM device; typical address busses today are about 15 bits wide. (3) A control bus is composed of the row and column strobes, output enable, clock, clock enable, and other similar signals that connect from the memory controller to every DRAM in the system. (4) Finally, there is a chip-select network that uses one unique wire per DRAM rank in the system and thus scales with the maximum amount of physical memory in the system. Chip select is used to enable ranks of DRAMs and thereby allow them to read commands off the bus and read/write data off/onto the bus.二、中文翻译JEDEC SDRAM 使用传统的 DRAM 系统组织方式，如前所述并在图 7.6 中展示。这里有四种不同的总线，按功能分类——在这种组织方式中，“内存总线”实际上由独立的（1）数据、（2）地址、（
