| Abstract: | 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. |
