Abstract: 1,037,633. Permanent data stores. INTERNATIONAL BUSINESS MACHINES CORPORATION.. July 4, 1963 [July 10, 1962], No. 26503/62. Heading G4A. In a read-only memory capacitive couplings are formed between drive lines D1 to Dn and sense lines CP to CZ produced by photographic techniques on a sheet of epoxy-glass or paper. The sense lines are broad and where a capacitive connection is wanted the drive lines are broadened as at C1 to form the other electrode. The Specification also describes selection circuitry which is such that a drive line presents the same impedance to a drive pulse for any number of capacitive connections.
