|  | G11C |
Note(s) This sub-class deals with devices or arrangements for storage of bits of information: in which no relative movement takes place between an information storage element and a transducer; which incorporate a selecting-device for writing-in or reading-out the bits of information into or from the store. In this sub-class, a storage element is provided with means for writing-in and reading-out at least one item of information. Elements not adapted for storage and not provided with such means are classified in the appropriate sub-class, e.g. of Fulltext... Hierarchy... Expanded...H01, Fulltext... Hierarchy...
