摘　　要：长期以来,国内流行的某些计算机组成原理方面的教材存在两个错误,其一是相联存储器不按地址寻址的问题,其二是多模块交叉编址存储器带宽的计算问题。本文对这两个错误进行分析和探讨。指出了(1)按地址寻址是相联存储器不可缺少的功能;(2)交叉存储器的带宽约为顺序存储器带宽的m倍,m为模块数。Too long-term misconceptions have been introduced by some popular domestic text books on the principles of computer organization. One is that the associative memory is not addressed via address, another concerns the calculation of the bandwidth of multi-module cross addressing memory. This article attempts to initiate discussions on these two misconceptions by verifying two points： 1） being addressable via address is an indispensable function of the associative memory, and 2） the bandwidth of multi-module cross addressing memory is m times larger than that of sequential memory, in which m is the number of the modules.
