计算机主存的一种故障检测方法

An Approach for Fault Detecting of RAM’s in Computer Main Memory

介绍一种采用特征矩阵对计算机主存中存在的ｓ—ａ—１，ｓ—ａ—０，以及桥接故障的检测方法，讨论了该特征矩阵的存在条件，作为示例给出了对按字节组织的主存进行故障检测的特征矩阵。

This paper introduces an approach that uses the characteristic mains to de tect the faults on the s-a-1, s-a-0 and bridging faults existing in computer’s main memory, and discusses the existing-conditions of the characteristic mains. As an example,a characteristic matrix of the fault-detecting for the main memory ananged by bytes is given.
