Among the components that decide about speed and reliabiliy of a computer, the memory modules occupy a crucial place. As bus speeds are constantly increasing, the technical difficulties faced in manufacturing synchronous DRAM are increasing exponentially to the incremement in bus speed. The reason for this is quite obvious, the higher the bus speed, the shorter is the time that is available for completing reliable data release within one complete clock cycle. In a 100 MHz environment this interval is the 100 millionst part of one second, that is 10 ns and most DIMMs offered today that comply with the PC 100 standard do not have any problems with this.
However, if one takes a look at the standards that will be implemented later this year, the bus speed will most likely be raised to 133 MHz as projected by Intel's Camino chipset, not to mention the AMD K-7 systems that may run at 200 MHz bus speed, once they are fully mature.
As stressed in several other articles on LostCircuits, data transfer from the system bus remains still the bottleneck in high power computing since most modern applications, particularly in a multitasking environment, require enormous amounts of data to be transfered from the system RAM to the CPU. If the data transfer is limited, the best and fastest processor cannot deliver adequate performance, for the simple reason that it doesn't know what to do with all the power.
