Abstract: 1,223,934. Magnetic storage arrangements. HONEYWELL Inc. 19 July, 1968 [24 Aug., 1967], No. 34676/68. Heading H3B. A selection circuit for a random access magnetic store 10 is arranged to simultaneously energize a single X or Y line threading ferrite cores 12 in each of two groups 1A-1D and 2A-2D. The two groups of core lines are connected at one end through decoupling diodes 29A, 29B to two pairs of switches 28A, 28B and 30A, 30B. Under the control of a memory address register 20 and a decoder 22, one switch of each pair is conductive at any one time and the groups receive potentials selected from + V and - V. The other ends of the core lines are connected to ground reference potential through resistors 62, and additionally each core line in one group is connected with the corresponding core line in the other group to a pair of switches 31A, 31B ... 31G, 31H. The memory address register operates two of the latter switches at any one time, one each from a different pair, and the other ends of two lines in each group receive potentials selected from + V and - V. The connections of the various switches are such that a potential difference between the opposite ends of the core lines is obtained for a maximum of two core lines, one from each group. The read or write current which flows as a consequence is in opposite directions in the two groups as shown at 64, 66. The switches are controlled through logic circuits 38A-38D and 46A-46H which receive the decoder outputs 24-1 to 24-8, read and write signals RD, WR from a timing unit 26 and the binary digit data 1, data 2 to be written into each group. The writing information is supplied by a memory buffer register 18 to the logic circuits 38A-38D alone through gates 33 and 34. For reading, both selected core lines carry current as shown at 64, 66. For writing, the direction of current is reversed for recording a binary 1; for recording a binary zero the potential at both ends of a line is the same and no current flows.
