从目前的市场价格不难看出SDRAM已经穷途末路,严重的内存带宽瓶颈使得我们必须寻找SDRAM的替代者。众多解决方案中,最典型的就是Intel支持的Rambus内存和VIA支持的DDR内存。Rambus内存是通过很高频率的串行传输来实现高带宽的,但是这种内存的制造工艺要求很严格,目前来说还不能有很高的成品率,因此也 From the current market price is not difficult to see that SDRAM is dead end, serious memory bandwidth bottleneck makes us have to find an alternative to SDRAM. Among the many solutions, the most typical are the Rambus memory supported by Intel and the DDR memory supported by VIA. Rambus memory is achieved through high-frequency serial transmission to achieve high bandwidth, but this memory manufacturing process is very strict, so far it can not have a high yield, and therefore
