A mathematical model for simulating pulse propagation in ferrite core memory arrays is described. Although specifically developed to analyze 3-dimensional arrays, the model is sufficiently general to give a satisfactory analysis of pulse propagation, waveform deterioration, and noise generation in a wide variety of memory configurations. The model treats the memory as a generalized, mutually coupled, multiconductor transmission line system. Insofar as is possible, the transmission line parameters are calculated from the array geometry, thus leaving only a small number of parameters that must be supplied empirically. Following a discussion of the equations which define the model and the methods by which they are solved, a sample array calculation is given to illustrate the kind of information that can be obtained from the model.
