Title: Improvements in memory systems for data processing devices

Abstract: 919,964. Digital data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 27, 1961 [Dec. 27, 1960], No. 46223/61. Addition to 886,889. Drawings to Specification. Class 106 (1). The parent Specification is concerned with scatter read or write operations. In a scatter read operation data from a single block in memory is transferred to a number of small blocks each defined by a record control (record definition, RDW) word. A programme instruction specifies the read scatter operation, and defines the address of an index word and the first of the RDW's. The index word defines the first address of the block from which information is to be read. The RDW contains a sign, and the first and last (start and stop) addresses of a small block into which part of the large block is to be read. In operation, the index word address is staticized and the start and stop addresses of the RDW. In each cycle a word is taken from the address on the index word and stored at the start address, after which the index word and the start addresses are incremented by one. The start and stop addresses are compared and when these are equal the sign of the RDW is taken into account. If the sign is negative, the read scatter is concluded, if positive, a new RDW defining the next small block, is taken from the address in the programme instruction plus one. Clearly, if the small blocks are each to contain one word, i.e. if the large block is to be scattered at spaced addresses, as many RDW'S as there are words in the large block are necessary. According to the present Specification two positions of the RDW define an increment to be added to the start address, so that for such an operation only one RDW is needed.
