自从英特尔公司于一九七一年研制出第一台微型计算机4004以来,它一直在以惊人的速度发展着,观已出现32位微型计算机。但是,随着集成度的迅速提高和电路尺寸的一再缩小,电路内部每个元件的散热量严重地抑制了VLST的发展。为了突破这一障碍,提高系统的可靠性;很多半导体厂家纷纷转向功耗低微的CMOS技术的开发,加快微型计算机的CMOS化的步伐。口前,CMOS已呈现出取代NMOS和TTL的趋势。这主要是因为它有一系列优点。
Since Intel Corporation developed the first microcomputer 4004 in 1971, Intel Corporation has been growing at a phenomenal rate with the emergence of 32-bit microcomputers. However, with the rapid increase of integration and the shrinking of the circuit size, the heat dissipation of each element in the circuit seriously inhibits the development of VLST. In order to break through this obstacle and improve the reliability of the system, many semiconductor manufacturers have turned to the development of CMOS technology with low power consumption to speed up the pace of the CMOS of the microcomputer. Before the mouth, CMOS has been shown to replace the trend of NMOS and TTL. This is mainly because it has a series of advantages.
