随着高速计算机的发展,需要研制存取时间小于1微秒的大容量超高速存貯器。提高磁心存储器的电流选择比可以达到这个目的。已经证明,采用多度电流重合法,将在存储系统的结构及操作方式方面引起重大的变革。因此,普通磁心选择开关已经不能胜任。本文介绍了一种双磁心开关,利用它可以顺利地来解决一系列在多度重合法中所产生的各种开关问题。本文还介绍了一个存储容量为10,000字(每字40位)的磁心存貯器,当选择比为3:1及7:1时,测得的存取时间分别为1微秒及0.8微秒(后者还可以缩短到0.6微秒);除了分析这个存貯器的工作原理以外,文中并附有实测的波形图。
With the development of high-speed computers, it is necessary to develop large-capacity super-speed memory with access time of less than 1 microsecond. This can be achieved by increasing the current selection ratio of the core memory. It has been demonstrated that the use of multiple current coincidences will lead to major changes in the structure and operation of storage systems. Therefore, the ordinary core selector switch is not competent. This article describes a dual-core switch that allows you to successfully troubleshoot a wide range of switching problems that arise in the case of multiple coincidences. This article also describes a core memory of 10,000 words (40 bits per word) with measured access times of 1 microsecond and 0.8 microsecond at a choice ratio of 3: 1 and 7: 1, respectively (The latter can also be shortened to 0.6 microseconds); In addition to analyzing the working principle of this memory, the text is accompanied by a measured waveform.
