一 半导体存贮器是六十年代中期问世的一种新颖存贮器件,它是大规模集成电路(LSI)中最有代表性的产品,其发展速度超过整个半导体工业发展的平均速度。由于它具有速度快、功耗低、体积小、成本低、可靠性高、外围电路简单等优点,因此近年来正有力地冲击着整个计算机存贮系统领域。表1、表2列出1976～1981年美、日、西欧半导体存贮器市场展望,从中看出其销售概况。1977年美国半导体存贮器的销售额达到6.32亿美元,而1971年只有0.7亿美元,即六年内增加了9倍。半导体存贮器在整个集成电路中的比重已由1971年的12％增长到1977年的30％。
A semiconductor memory device was introduced in the mid-1960s as a novel memory device. It is the most representative product in large-scale integrated circuits (LSIs) and has grown at a rate exceeding the average speed of the entire semiconductor industry. Due to its advantages of fast speed, low power consumption, small size, low cost, high reliability and simple peripheral circuits, it has been aggressively attacking the entire computer storage system field in recent years. Table 1, Table 2 lists the 1976 ~ 1981 United States, Japan, Western Europe semiconductor memory market outlook, from which to see the sales profile. In 1977, sales of semiconductor memory in the United States reached 632 million U.S. dollars, compared with 70 million U.S. dollars in 1971, an increase of 9 times in six years. The proportion of semiconductor memory in the entire integrated circuit has increased from 12% in 1971 to 30% in 1977.
