计算机正以迅猛的速度往前发展。作为计算机硬件两大支柱的微处理器和存储器,都有长足的进步,但仍面临着一些问题。最新的微处理器200兆赫的Pentium Pro(高能奔腾,俗称686)集成电路上的线宽只有0.35微米,而且不久便会有线宽0.25微米和0.18微米的器件面世。但从出现集成电路以来,集成度通常每三年便翻两番(相当于线宽缩小到一半),然而近10年来微处理器却未以这样快的速度发展。人们不禁要问,现在的硅半导体技术是否还能支持计算机高速发展?在存储器方面也有类似情况。目前计算机存储技
Computers are moving at a rapid pace. As the two pillars of computer hardware, microprocessors and memory, have made great progress, but still face some problems. The latest microprocessors have a line width of only 0.35 microns on the 200-MHz Pentium Pro (high-energy Pentium, commonly known as 686) integrated circuit, and will soon have 0.25-micron and 0.18-micron line width devices available. However, since the advent of integrated circuits, integration usually quadrupled every three years (equivalent to half the line width), however, microprocessors have not grown so rapidly in the last decade. People can not help but ask, is the current silicon semiconductor technology can also support the rapid development of computers? In memory there is a similar situation. The current computer storage technology
