近两年来,半导体存储器已经以要取代磁心存储器而出名了。集成电路虽存在近十年了,但它的生产技术和可靠性是在近几年才达到很高水平的,而且已设计出18引线或22引线的双列直插式封装的1K、2K 或4K 的存储器硅片。为使磁心存储器在价格/性能比方面保持对半导体的竞争能力,设计者必须利用中规模集成电路的优越性,来进一步降低电子线路的价格。近几年来,磁心体本身已变得便宜些,而且目前对此仍在努力。采用高密度排列 In the past two years, semiconductor memory has become famous for replacing core memory. Although integrated circuits have been around for nearly a decade, their production technology and reliability have been very high in recent years and they have been designed for 18-lead or 22-lead dual in-line packages of 1K, 2K or 4K memory silicon. To keep core memory competitive with semiconductors in terms of price / performance ratio, designers must take advantage of medium-scale integrated circuits to further reduce the price of electronic circuits. In recent years, the magnetic body itself has become cheaper, and is still working on this. High-density arrangement
