本文描述了一台容量为1024字×100位的存储器。存储单元由铁氧体磁心(外径=30密尔,内径=10密尔,厚度=10密尔)构成,每位用两颗磁心,采用了线选法方案。在存储板的穿线工作上,部分地利用了印制导线,因此,简化了磁心的穿线工作。存储器的工作周期为450毫微秒。文章还介绍了把位线当作一组相互耦合的平行传输线并予以适当的匹配,是一种新的方法。同时指出,利用位线上的不同类型的波传播可能是获得现代存储器的高速操作的一种途径。
This article describes a memory capacity of 1024 words × 100 bits. The memory cell consists of a ferrite core (OD = 30 mils, ID = 10 mils, thickness = 10 mils), with two cores per bit, using a line selection scheme. In the threading operation of the memory board, the printed wiring is partially utilized, thereby simplifying threading of the magnetic core. The duty cycle of the memory is 450 nanoseconds. The article also introduces a new approach to using bitlines as a set of mutually parallel, parallel transmission lines and matching them appropriately. At the same time, it is pointed out that the use of different types of wave propagation on a bit line may be one way of achieving high-speed operation of modern memories.
