G11C17/126 - CPC Classification

Classification description:

Read-only memories programmable only once; Semi-permanent stores, e.g. manually-replaceable information cards using semiconductor devices, e.g. bipolar elements in which contents are determined during manufacturing by a predetermined arrangement of coupling elements, e.g. mask-programmable ROM using field-effect devices Virtual ground arrays
