1,154,458. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORP. 4 Nov., 1966 [30 Nov., 1965], No. 49545/66. Heading G4C. In a memory system each word has one bit stored in each of a plurality of storage sections which have respective control means operable in parallel under control of an address register which specifies a plurality of word storage locations and the direction along which they lie to transfer a plurality of words simultaneously between the storage locations and a multi-word data register. The storage sections may each be a plane (matrix) of magnetic cores, thin magnetic film elements, electronic flip-flops or capacitor diode units. The word positions read out (or written into) simultaneously must be adjacent locations intersecting the same one of either one of the X-lines (in a storage section) or one of the Y-lines. The address register specifies in respective fields (A) whether the locations are along an X or a Y line; (B) the number of the line; (C) the position of the first required location on the line; (D) the number of required locations (words). Data is transferred between the data register and the storage sections via shifters (comprising gates only) controlled by the last two fields of the address register. Use in a multi-processor computer is mentioned.
