Abstract : Is it possible to create an electronic computing machine of such dimensions as the modern ones have, but working twice or three times as fast. It is possible but for this it is necessary to construct a memory device not with two electrically stable states, as in the case of the existing elements, but three or four. Not long ago in the Soviet Union there was created such a two-opening ferrite magnetic element, the 'sager.' It has four stable states. Simultaneously, there is determined a complex of electrical signals, each of which corresponds to one of four symbols and serves for transmitting information from one memory element to another. The 'sager' possesses the advantage that the information is passed from one element of the memory to another only along one channel of communication for one cycle, which assures the maximum rapidity of action. These properties make it possible to use the 'sager' for quarternary computing machines. Research has shown that by simple technical media there can be distinguished in one circuit only four states - absence of current, movement of current in one direction, movement of current in the other direction, and alternate movement of the current in the two directions. The use of other combinations of electrical signals requires either the creation of apparatus with a great number of cycles or the introduction into one channel of communication of complicated logic devices for distinguishing the signals transmitted from one memory element to another.
