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.
