Abstract :
The representation of the switching characteristics of the ferrite memory core by flux-charge curves and the derivation of significant design or application parameters for a new, undeveloped ferrite memory core are described. The technique used is that of appropriately scaling flux and charge by a computer program. User options permit computation of signal and noise amplitudes and waveforms, read current and percent flux switched, core height and threshold, or outer and inner diameters, depending on the information available as input data. Effects of parameter tolerances can be evaluated, and technology advances effecting device improvement can be indicated and accommodated.
