Abstract : The operation of a square-loop-ferrite storage element is investigated; two or more cores linked together are required for each binary digit. The core operation is described by a system of equations, and formulas are given for turnover currents, which allow for the turnover-current front-rise time. These formulas permit evaluating the effect of core parameters and link resistance on the speed of operation. Various modifications of the write-read systems are compared by the complexity of their control circuits, the number of exciting devices for number-link access, by their rates and the requirements of exciting fields under write-read conditions. The results of analysis are tabulated.
