摘　　要：通过对带记忆逻辑模型进行分类,给出了混合型带记忆逻辑的概念,指出了这种由累加器和搅拌器混合而成的带记忆逻辑的优点,分析了将基于单比特操作的混合型带记忆逻辑推广到整字带记忆逻辑的实用性.概述了整字带记忆逻辑设计的基本要求.给出了一种单字节输入输出带记忆逻辑具体实例,并描述了这类逻辑在序列密码算法设计中的应用.By classification of the models of combiners with memory, a new type of such memorable logic, the combination of addition and blender, was proposed and its advantage was presented. Such a type of memorable logic could be popularised to word-oriented operations and widely be used. The essential demand and rules for the design of word-oriented combiners with memory were briefly discussed. A detailed example which is byte-oriented was presented and the usual ways of application was exemplified.
