Introduced: January 1990
Full Title
Full titles differ between systems:
IPC:
Erasable programmable read-only memories > electrically programmable > using variable threshold transistors, e.g. FAMOS
CPC:
Erasable programmable read-only memories (G11C14/00 takes precedence) > electrically programmable > using variable threshold transistors, e.g. FAMOS
Of 4 combined children, 0 exist in both systems.
4 codes are CPC-only extensions.
