在过去十年中,所有的计算机存貯器几乎百分之百采用了铁氧体磁芯作为存貯元件。但是,随着薄膜技术和整体电路技术的发展,出现了薄膜存貯器和整体电路存貯器,它们具有速度快、成本低、以及一次可以制成一个大存貯矩阵的特点。由此,铁氧体磁芯存貯器的统治地位已开始发生了动摇和受到排挤的威胁。 在1965年美国秋季计算机会议上,很多整机和存貯器设计者对这样一个问题发生了兴 Almost a hundred percent of all computer memory has used ferrite cores as storage elements in the past decade. However, with the development of thin film technology and overall circuit technology, thin-film memories and integrated circuit memories have emerged that are fast, inexpensive, and capable of forming a large memory matrix at a time. As a result, the dominance of the ferrite core memory has begun to be shaken and threatened by displacement. At the 1965 Fall Computer Conference in the United States, a number of machine and memory designers were excited about such a problem
