G11C17/146 - CPC Classification

Classification description:

Read-only memories programmable only once; Semi-permanent stores, e.g. manually-replaceable information cards in which contents are determined by selectively establishing, breaking or modifying connecting links by permanently altering the state of coupling elements, e.g. PROM Write once memory, i.e. allowing changing of memory content by writing additional bits
