DIFF Subgroup
G11C 11/02 using magnetic elements
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor > using magnetic elements
CPC:
Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor (G11C14/00 - G11C21/00 take precedence) > using magnetic elements
IPC and CPC are identically structured here. All 7 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
