PC133 standards battle with Rambus

rialPresenceDetect),[link widoczny dla zalogowanych], the so-called SPD is an 8-pin EEPROM, the memory on the chip than a grain of rice that is it. Memory makers are using the memory chips write the basic information in advance EEPROM, the system can correctly identify the memory SPD, which with the right methods to drive it. Without SPD, the system BIOS only by testing the method to identify or guess the basic information of the memory, easily lead to system instability. Memory using 6-layer circuit boards, but few of PC100 memory,[link widoczny dla zalogowanych], 6 laminates are basically 4 laminates. Relative to PC104) is, PC133 specification change is the most faster too. PC100 memory chips called for at least 10ns, and the PC133 in the standards to 7.5ns, PC133 this is the minimum requirement, the actual use of Taiwan in large numbers 7ns memory. PC133SDRAM data transfer rate l06GB / S (algorithm 64bitx133MHz = 106GB / s), has been able to basically meet the needs of AGP4X than RDRAM Although there is still a gap, but look at the current range of applications, PC133SDRAM have been able to meet the actual needs, PC133SDRAM main advantage is its moderate price. It should actually be regarded as an enhanced version of PC100SDRAM in structure PC133SDRAM and PClO0SDRAM no difference. This means that memory manufacturers simply produce the original production line a little PC100SDRAM transformation can be put into mass production Pcl33SDRAM. Obviously, this is more consistent with the memory manufacturers to ensure return on investment purposes. And from the user point of view. When the product performance to meet the application requirements, determine the purchase price of seed as the determining factor. Thus, PC133SDRAM optimistic about market prospects can even terms with the technology. Benefit for the purpose of different users PC133, due to its manufacturing process and cost did not change much compared with PC100, the memory manufacturers have been widely supported. In fact, VIA is not pushing the next generation memory PC133, SDRAM �� SDRAM �� but the correct name for the DDRSDRAM (DoubleDataRateSDRAM), DDRSDRAM sDRAM now improved by the next generation memory technology out. DDRSDRAM no different from the core and SDRAM, The difference is DDRSDRAM can increase the speed and compatibility with SDRAM DDRSDRAM a total of two different places: (1} DDRSDRAM use of more advanced synchronization circuit; (2) DDRSDRAM use the Delay-lockedLoop (DDL ) to provide DataStrobe signals, can accurately located in the list of reasons for the different pairs of memory modules are inserted into the data. In addition, DDRSDRAM order to be able to 2 times faster, it allows the data in both rising and falling edge trigger on DDRSDRAM , the bandwidth can be 2 times larger than SDRAM. And DDRSDRAM bandwidth in the 100MHz system will run up to 1.6GB / s. By the end of 2000, DDRSDRAM frequency will reach 266MHz, the output frequency up to 533MHz. With more and more memory, the memory manufacturers to Pcl33 competition, Intel insisted Rarebus seems a bit highbrow. but for lntel for persevering. because Rambus required to pay a certain amount of production royalties, technology licensing fees royalties and profits, as Rambus partners. If Rambus popular, Intel will be rolling in money. In addition,[link widoczny dla zalogowanych], the increase with the Inte1 support and reduce the cost of RDRAM, will gradually expand its market share, can become mainstream, But the memory vendors judged to be the market and for the PC133 RDRAM should be careful, most insurance way is to foot boats. Indeed, as the increasingly fierce market competition,[link widoczny dla zalogowanych], and now more and more hardware vendors really bad the day before. But no matter what the future will, the ultimate beneficiaries are the user units. �� Responsibility silk series: Sun Jie sit cross-legged bundle of a T ~ gii ~ @ cewccn responsibility for the United States Code.
