铁氧体存储器的工作温度范围主要是由磁心的破坏电流及输出的温度系数而决定的。新的锂铁氧体磁心的破坏电流及输出特性与温度无关。与普通类型磁心相比较,利用这类磁心可在实际上扩大记忆元件的工作范围。给出了两种不同尺寸(一种是外径50密耳、内径30密尔;另一种是外径30密耳、内径18密尔)的实用宽温度范围磁心的典型的温度变化时的响应特性。叙述了设计在特定温度范围内工作的磁心所使用的方法。概述了含有4096个宽温度范围磁心的矩阵存储板的工作特性。
Ferrite memory operating temperature range is mainly determined by the core of the current and the output temperature coefficient of failure of the decision. The destruction current and output characteristics of the new lithium ferrite core have nothing to do with temperature. Compared with the ordinary type of core, the use of such cores can actually expand the working range of the memory element. Given the typical temperature variations in practical wide temperature range cores of two different sizes, one with an outer diameter of 50 mils and an inner diameter of 30 mils and the other with an outer diameter of 30 mils and an inner diameter of 18 mils, Response characteristics. Describes the method used to design a core that operates within a specified temperature range. The operating characteristics of a matrix memory board containing 4096 cores with a wide temperature range are outlined.
