1.RDRAM is a kind of memory developed by RAMBUS Company in the United States, and its full name is RAMBUS DRAM
2. This kind of memory uses 16-bit serial mode to transmit data, and intel strongly supported it at that time, but this technology cost is high, and since intel supported it, it definitely wanted to make more profits with its monopoly position. Therefore, others will be charged patent fees for producing this kind of memory, just like the feeling of ios and Android. In addition, ddr memory is easy to produce, and it can reach 64-bit transmission bandwidth at no other cost to the manufacturer, and its performance is not much worse. Therefore, the user finally chose DDR < P > 3. The transmission methods of DDR and rdram are different, but there should be no better. Just like the hard disk interface, serial port was used in the past, and data transmission was slow because of the low frequency at that time. Later, it was changed to parallel port, so it was naturally fast to transmit multiple data at the same clock. Later, because the parallel port interference can no longer increase the frequency, and the bus frequency has increased a lot, so the serial port was used again. Can you say who is better with parallel port? No one can tell whether the memory will use the original technology in the future, but there is no big bottleneck now, and of course there will be no new one in terms of profit.
