二十多年来,现代科学技术的迅速发展,对电子计算机提出了愈来愈高的要求,而电子器件的不断更新又为计算机的发展创造了极其有利的条件。一直在计算机存储系统中占主导地位的磁心存储器,近几年来也受到了半导体存储器发展的影响,并部分地被半导体存储器所代替。但是磁心存储器在可靠性方面,特别是其非易失性方面,具有显著优点。在容量、成本、体积等方面也获得了不断发展。例如1976年,美国生产了一种巨型磁心存储模块,容量为256千字节,周期1.3～1.5微秒,体积
In the past two decades, the rapid development of modern science and technology has raised higher and higher demands on electronic computers. The continuous updating of electronic devices has created extremely favorable conditions for the development of computers. The core memory, which has been the dominant memory in computer storage systems, has also been affected by the development of semiconductor memory in recent years and is partially replaced by semiconductor memory. However, magnetic core memories have significant advantages in terms of reliability, particularly in terms of their non-volatility. In the capacity, cost, size and other aspects have also been evolving. For example, in 1976, the United States produced a giant magnetic core storage module with a capacity of 256 kilobytes and a period of 1.3-1.5 microseconds. The volume
