G11C 16/10 Programming or data input circuits
Introduced: January 2000
Full Title
Full titles differ between systems:
IPC:
Erasable programmable read-only memories > electrically programmable > Auxiliary circuits, e.g. for writing into memory > Programming or data input circuits
CPC:
Erasable programmable read-only memories (G11C14/00 takes precedence) > electrically programmable > Auxiliary circuits, e.g. for writing into memory > Programming or data input circuits
Of 6 combined children, 4 exist in both systems.
2 codes are CPC-only extensions.
IPC defines codes here since 2000.
