SJ-55/40机存贮容量为128K×16字,采用以8K×16字为模的结构,共有16块磁芯板分成2个磁芯体(每体8块)。每个体设一套接口和控制电路。在该控制电路中中,我们对存贮板,的选板功能做了一点改进。就是改变了以往那种让内存各单元区域与固定磁芯板相对应的方式,代之以依据磁芯板是否缺1块,而分别与相邻2块磁芯板相对应的方式,亦即当对应某一存贮区域的一块磁芯板出现故障,拔下检修 SJ-55/40 machine storage capacity of 128K × 16 words, the use of 8K × 16 word mode structure, a total of 16 core board is divided into two core body (8 per body). Each body has a set of interface and control circuit. In this control circuit, we made a little improvement on the board selection function. Is to change the past that the memory cell area and the fixed core plate corresponding to the way, instead of depending on the core board is missing a block, and respectively adjacent to two core plate corresponding way, that is, When a core corresponding to a storage area of ​​the core failure, unplug the inspection
