The memory effect and correlations of the statistical and formative time delay in argon and synthetic air DC glow discharge at low pressure were studied. The memory coefficients and ratios and Pearson's and Spearman's correlation coefficients were determined, ranging from about unity at low relaxation times and vanishing at the saturation region of the memory curves (determined by the background ionization). It was shown that the statistical ts and the formative time delay tf are correlated variables and the positive correlation between them was confirmed experimentally and theoretically.
