Morphology
modified + Harvard + architecture
The phrase literally combines 'modified' + 'Harvard' + 'architecture', so a learner who knows those words can infer it is a changed/variant form of a system called the Harvard architecture. However, the crucial technical sense (how instruction and data memory are treated) depends on knowledge of what 'Harvard architecture' denotes; 'Harvard' as a proper name gives no semantic clue to the memory-design contrast. Thus the composition signals a modified type but not the specific technical meaning without prior domain knowledge.
Etymology
Modified Harvard architecture is a change to an old computer design where 'instruction memory' and 'data memory' were kept in separate rooms. One easy picture is that a 'door' was added between the rooms so a program can read or change instructions like data, so it means the 'instruction memory' can be used like the 'data memory'.
