INFORMATION STORAGE
 G11C
STATIC STORES (recording and playback of information by relative movement between a record track and a transducer G11B; pulse technique in general H03K, e.g. electronic switches H03K 17/00)
 G11C

Note(s)

  1. This sub-class deals with devices or arrangements for storage of bits of information:
    1. in which no relative movement takes place between an information storage element and a transducer;
    2. which incorporate a selecting-device for writing-in or reading-out the bits of information into or from the store.
  2. 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 H01, H03K.
