WebWhat is memoryless in the Poisson process is inter-event intervals (usually inter-event times). The Poisson distribution itself is the distribution of counts per unit interval. So you have a set of counts, but not the times (or whatever you're measuring events over). You don't have inter-event intervals to be memoryless about.
