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 detail ed example which is byte-oriented was presented and the usual ways of applicati on was exemplified.

Key words: cryptography, stream cipher design, combiners with memory, wordorie nted memorable logic
