Full titles differ between systems:

IPC:

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor > using electric elements > using semiconductor devices > using diodes, e.g. as threshold elements > using tunnel diodes

CPC:

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor (G11C14/00 - G11C21/00 take precedence) > using electric elements > using semiconductor devices > using diodes, e.g. as threshold elements > using tunnel diodes
